Jim Tull: Well, good luck with that right i'm gonna start doing fieldwork this this next month myself, if I can.
mark carter: yeah I think we're we're just behind.
mark carter: The State surveys just rolled on business as usual and and we good, though.
mark carter: i'm backup about I don't know 344 going.
Jim Tull: yeah yeah I talked to Chris he was having problems with the lab out there in Denver they add water pipe break or something.
yeah.
Jim Tull: yeah he couldn't you're right.
Josh Poole: All right, everyone let's go ahead and get started we'll get this ball rolling i'm trying to.
Josh Poole: To make my full screen here it's not cooperating so give me give me just a minute here.
Josh Poole: There we go okay great so i'm going to try and.
Josh Poole: pin our.
Josh Poole: Our our our leaders our fearless leaders to the main screen here alright so welcome everyone, it is nice to see such a spread of people, we have a decent number of y'all here today, so that is that is awesome.
Josh Poole: So basically this this field trip, I was asked to join in this with with Dr bill hames who is who is here with us as well.
Josh Poole: He actually has a short course to attend to so he won't be with us for a very long time, but he will be with us for at least a couple minutes so we'll do short introductions and then i'm going to kind of will pass it pass the ball to him, but basically this this field trip.
Josh Poole: It we are um.
Josh Poole: Let me back up real quick could on your on your screen on the bottom, could you just can we get a show of hands on who was actually able to to see the the field trip.
Josh Poole: That was able to watch it so far, all right 1234 all right, so a good number of you excellent i'm glad people watch it we put a lot of work into that so i'm glad that uh that some people were able able to see that so good so.
Josh Poole: In the video bill kind of gave an introduction on where the name came from.
Josh Poole: And if you watch the V realized that there's not a whole lot of other rocks that that we talked about so it's mostly violent is mostly shared rocks.
Josh Poole: And we kind of spread the still pulls where we're kind of we're honoring his work, of course, and that works spread from the southern terminus of the appalachian mountains and Alabama and Georgia, and then on the opposite polar end of that was up in Scandinavia Norway.
Josh Poole: So he kind of.
Josh Poole: straddle those two most of the focus was on southeastern geology and then bill hames took the reins and and carried us in his santa's sleigh on up to.
Josh Poole: to Scandinavia and so that's kind of what the future was mark is actually having difficulty getting into this into our current.
Josh Poole: Q amp a session he planned to be here and i've stepped away in the very beginning, because I was on the phone with him trying to get him walking through this he's having difficulty So hopefully the.
Josh Poole: The.
Josh Poole: The tech can the tech folks can help him with that, but anyways so what we're going to do now is just generally open it up um.
Josh Poole: i'm not sure if I have adjusted the screen or not um i've clicked on a lot of different things so.
Josh Poole: let's see so on on your screens hopefully what what you're seeing pinned is the speakers i'm not sure if everyone's seen that but.
Josh Poole: I didn't introduce myself on josh boy i'm a former student of March 2 poll, we have Dave van before with the state survey Alabama state survey, who worked under under mark, we have john went more also a survey that worked under mark will bill haynes with auburn university.
Josh Poole: close colleague, and then we also have Randy Catholic University of West Georgia has also worked closely with stone upon a number of projects so.
Josh Poole: we're going to do now is I guess will generally open up the floor for for questions and what first i'm going to pass it to bill really quick and if he has some some remarks or things he would like to say, and then, if you have a question.
Josh Poole: will handle the Scandinavian stuff first and then we'll go back to the southeastern stuff but while we have bill for the short time will pivot to that so bill would you like to.
Josh Poole: To add anything.
Josh Poole: Well, thank you, we have questions if you have questions again raise your hand and or put them in the chat.
Willis Hames: Thank you josh and I apologize for having a an appearance in another, you know short course in another venue in a second the.
Willis Hames: I think I can serve up a lot, by saying that Marcus of a native of Alabama has a degree from the University of Alabama and his master's thesis thesis advisor Dr toll is on the.
Willis Hames: Call with us as well, and there are a lot of connections, we go through life and their connections that we would think how how did these things get connected why Alabama and Scandinavia, but.
Willis Hames: Those really come back to his master's thesis advisor Dr tall and also Dr john bartley for his dissertation work and what I would say again if which which you already know.
Willis Hames: From the.
Willis Hames: know about Marcus he's been a dynamo for our program for student recruitment and he far and away holds up a record for the most graduate students and.
Willis Hames: Probably most at any one time and most throughout his career, I would venture to say and it's open a lot of opportunities for people in different ways.
Willis Hames: it's really helps make a name for our program helped establish an identity for our program and then he served as chair of for two tours of duty as well and.
Willis Hames: All those things really have compel us lots of contributions lots of people assistant to put this trip together and honestly, I think.
Willis Hames: Randy and I didn't have to do too much really there was a lot of enthusiasm by various people what's the ball got rolling.
Willis Hames: And what I can also do, though, is take responsibility for anything that got left out or anything that got dropped or anything that didn't make it we apologize for the frailties of our it prowess of josh to a great job putting the video together well and.
Willis Hames: Even the platform that we're trying to work off of this stepped into us.
Willis Hames: So, if I may hesitate there for a moment.
Willis Hames: And again, I apologize to head out in a moment, myself, but this discussion will continue, are there any questions that would like to ask them of field trip leaders.
Willis Hames: Have a learning experience, just to wait, let the of the Claudia belt on the wall and you know.
Josh Poole: Violence for someone to answer.
yeah.
Michael Thonis: Okay, I can break the ice.
Okay.
Michael Thonis: I I live in Boston and.
Michael Thonis: ringing the Boston area there is what most of the maps call say is a mile night.
Michael Thonis: You know it's about a two or three mile wide so it's it's may thick generally whatever that means in this in this.
Michael Thonis: context and it's you know you can't really I mean the fabric is so messed up you can't see anything but.
Michael Thonis: You know, it always just taking a break up in your hands but doesn't it's it's you know it's solid.
Michael Thonis: But the causes, I can come to describing it but it's generally believed, I think, to be.
Michael Thonis: The.
Michael Thonis: You know the a brush created zone, I guess, a you know, a highly faulted zone that represents the suture the collision between abalone.
Michael Thonis: And Lorenzo.
Michael Thonis: So i'm standing right now and i'm standing on an East of it by a couple miles i'm standing on abalone are right now.
Michael Thonis: But I don't have to draw like as you walk over to practically and beyond that zone it's about two or three miles wide, as I said, and then and then you're you know you are clearly in the ratio, because most of those rocks have been tainted, as you know, as cambrian ordovician.
Michael Thonis: So I guess is that is that generally thought to be sincere.
Michael Thonis: So if you are Scandinavia and some of you are Alabama is, would you guess that that zone that mile an hour zone here between abalone and lorenza is just you know part of that.
Willis Hames: I it's related, of course, and and i'll show up in others may have more immediate knowledge, but as we go eastward in a lot of the states, we come across fundamental train boundaries to things that were not part of North America.
Willis Hames: Proper and not not part of lunch, yet you know more and more correctly and that have been created on and the trains of.
Willis Hames: Eastern most doing ones are probably coming on after Arc trains head accreted and they represent something else entirely, I know about fossil occurrences, to the south things like that to help, but does anyone else have a comment.
Dane VanDervoort: That long.
hey.
STELTMG: Everyone yeah finally got him.
Josh Poole: Excellent.
Josh Poole: Good deal.
Josh Poole: All right, awesome.
STELTMG: yeah honored to be here, thank you all for for showing up and.
STELTMG: Now leaders and all for doing this for me I don't mean to interrupt there was a question and answer session go in there, from what I gather.
Josh Poole: Oh you're you're fine we're glad to have you here, we did kind of a brief introductions and we're yeah like we're fielding questions now and.
Josh Poole: You might get up with this bill, do you want to recap that question.
Willis Hames: Bob i'm just telling mark it's perfect timing, because it is private chat super secret.
Willis Hames: Because i've got a sign off right now.
Willis Hames: So i'm.
Willis Hames: Market was a question about terrain accretion and the Eastern appalachians case example in New England and the Massachusetts region but question really could apply to the Carolina terrain, of the southern appalachians as well that was from.
Willis Hames: Of.
Michael Thonis: My phone is.
Willis Hames: On us thank you bye.
Michael Thonis: I think another version of the question is.
Michael Thonis: What really is a mile a night.
STELTMG: My my advisor john's barley taught me when I was in North Carolina he said that if you at that time that was in what 19 8082 or so, he said that if you want to get into a fight you go to a bar full of structural geologists and sandwich perfect definition of a model and.
STELTMG: that's why i've always thought of it that.
STELTMG: You know I want to.
STELTMG: it's kind of funny because I got interested in my guides when out when I left, Norway and came to the Alabama state geological survey.
STELTMG: And I got interested in the area around all over and actually in the pine mountain in the pilot and Linda is i'd read i've.
STELTMG: read about this model and it sounds that while we go Rock in bartlett's theory and all those for so long, and I was curious to go have a look at those and.
STELTMG: And I went down there and just had a wonderful time the problem in Norway is that most of the the terrain, or at least the the major thrust boundaries, there are higher grade really sin or pre metamorphic kinds of boundaries that are real cryptic kinds of things and.
STELTMG: I remember john bartley telling I think it was john may have been Jim that one of them talking with.
STELTMG: Someone from who is working in Norway and they were bragging about their Milo nights and.
STELTMG: john I think it was john said that when you should see said that if you show those to a southern appalachian geologists they would live life that she.
STELTMG: Did apparently the modernized are so nice down here that, and what I found was that that's that's pretty to I had to get good experience working in the ones, flying in the pine mountain window that's where I cut my teeth I guess.
STELTMG: I don't think that answers your question, Michael but.
Michael Thonis: I didn't expect a real you know.
Michael Thonis: Perfect no that was perfect, I think, maybe to about my Luddites is i've always wondered if.
Michael Thonis: You know my last night it doesn't I know it's a structural term so it doesn't necessarily imply that metamorphosis.
Michael Thonis: But it does seem to me that the environment in which it's happening could be at least under a lot of pressure and I wonder if you don't, it is not in the in the broadcasting category of most nights there are.
Michael Thonis: Other things you know granular lights, for example, are they ready, if you will have to the field, how do you know what tomorrow night, other than it's a structural thing, do you know what as it is because there's a pathological thing to it.
STELTMG: yeah that's that's true the.
STELTMG: There yeah there are but a matter of both.
STELTMG: In my opinion, we are.
STELTMG: In southern appalachians I find that they are zones of their their certainly zones of.
STELTMG: Company combination of grains of rain sizes that they get smaller it's you get into the sheer zone and stretched.
STELTMG: In Norway, the ones that I dealt with were pretty high temperature kinds of ones, particularly up in the the thrust snaps where they're just a lot of political rocks in a fairly high grade.
STELTMG: We ran into some interesting my nights and actually brutal fractures in the local region in western part of.
STELTMG: The basement complex in in Norway in northern Norway, the low food and islands there where that's where they're actually jack face she's.
STELTMG: cheers zones and actually aquagenic face she's there brittle faults, where the green lights to fractured in as thought that deck digitizing fluids, is what caused the fracturing of those rocks and then they aided in the plastic development of modeling nights after the initial.
STELTMG: rebel fracturing of the of the granular lines so they're they're certainly the petro illogical.
STELTMG: distinction between them they're green light face she's in aquagenic faces here's what we're looking at there in the basement I got involved with Dave marker at the University of Kentucky and he is the one who.
STELTMG: I was attracted to his work, particularly on suit attack lights because they're actually giant face she's crystal lights and some of those in some of the suit attack lights in that area and.
STELTMG: they're not as spectacular as the ones that were developed down in southern are in western Norway in the Bergen arcs that there's some good examples of the mandate is a quantitative.
STELTMG: pathologist quantitative metamorphic pathologists he did some pressure temperature work on some of those suit attack lights as well, some of that model nights and.
STELTMG: He did a lot of that metrology work for us and.
STELTMG: Just fantastic rocks that would spectacular to see you know those kinds of relationships in its food and basement terrain, where they're just various there and North this icon places the very large Platonic.
STELTMG: coarse grained Platonic rocks in their grants and loans up monster nights and so on, so and that's where Jim Jim introduced me to the food and islands, Jim tall that's where he did his doctoral dissertation or record birchfield when Clark was at rice university that's where I got.
STELTMG: So I had a little dose.
Of.
STELTMG: things to do.
Jim Tull: hey mark this gym.
STELTMG: Okay do.
Jim Tull: i've got a question.
Jim Tull: Now that you figured this zoom technology out when you get get a chance, can you come down to tallahassee and walk me through it.
STELTMG: is blind leading the blind.
STELTMG: I learned, I had to learn some zoom when I had to teach my structure class last spring didn't have anybody replaced me, and so I have, I was happy to do that, like everybody else you know, I was.
STELTMG: I was pretty much captured by code, but we were in we were in nashville and my wife's stepmother was has health issues and.
STELTMG: So we went up there we're going to spend the weekend to help her and we got up there and we couldn't leave, so I was there for five weeks straight teaching structure, you know, and I learned zoom pretty quick there but i'm certainly no expert, as you can tell.
STELTMG: Okay.
Josh Poole: Okay, so mark mark Carter had a question before we get to that i'm probably putting my my foot in my mouth here and.
Josh Poole: Randy will probably say i've never told him that, and this may be the equivalent of throwing.
Josh Poole: A glass on the floor in the bar to start a start a brawl here and we have other people that may that may jump in at me but take to simplify the answer to your question, Michael about general Milo nights.
Josh Poole: I guess, we can generalize about saying that the the protocol, it may not be as important as the the textures we can certainly refine the definition based on politik rocks those for more file nights and whatnot but.
Josh Poole: As we increase metaphor for grade generally you know the the grant size increases, whereas when you increase monetization the green size will decrease so typically it's it's induced by sharing yeah well full of.
Josh Poole: rocks that are well fully aided with oftentimes share since indicators, but you have a reduction in grain size so have you as you get to the more high strained zones that that Protocol, it becomes more fine grained.
Josh Poole: And you can see that, as you move from inside the highest rate zone to the outside of becomes more more finer grain and you start to lose those sheer textures.
Josh Poole: So I don't want i'm hopefully no one's going to jump on my back, I hope, maybe stone pole or Randy or Jim can can chime in and say that was okay or Scott is already talking about, but maybe that is does that help Michael.
Michael Thonis: That does have, but I think, really, where I was heading on it is wondering whether or not there might not be.
Michael Thonis: It might not be things that were once mile and night zones, but you can no longer recognized as such, because the you know, because the amount of.
Michael Thonis: The amount of sharing the amount of micro granular converted to an infidel like Nice or something you know uncivilized just you know that it just.
Michael Thonis: becomes something that we then call something else but it's actually I kind of wonder, as we you know when you grow up you drive from Boston west to.
Michael Thonis: New York state you drive right across the Green and there are lots of and you see you know the road across her vivid on the turnpike and.
Michael Thonis: he's got a lot to get out but they're there they're very clear and.
Michael Thonis: In a constantly make fresh because they're constantly doing what roadwork and you can see lots of places that I think, at least from you know a few hundred yards away, they appear to be my own zones, you know they give another names.
Michael Thonis: Right very.
Josh Poole: Well, you may just have to stick your nose to the outcomes and then you said you can't but.
Josh Poole: As far as like changing the character characteristics, a rock and will and we'll move I know this is a mad I talk more move on to.
Josh Poole: marks question is second, but if you saw randy's presentation, the long island creek nice to Atlanta, we have.
Josh Poole: They have black knights white white knights but the long island creek Nice is just your typical grid nice, but in some of these magnetic zones, it turns white and it's almost just you know extremely markets and ultraviolet light so.
Josh Poole: it's a reduction in green side so so yeah potentially i'm ready, do you want to and.
Randy Kath: He has just been sprayed gosh.
Randy Kath: We see in the dark zone here in metro Atlanta going all the way down toward the Banda is the protocol, it has a profound influence on what the mile and I it's going to be.
Randy Kath: We see all different grades of highlight some of our ultra mile and I, and she can't even tell what they were.
Randy Kath: But if you go through a progression like in the long island, it will start to share and develop organs, you know, so we call it organizes and then.
Randy Kath: Those can continue to shear and start developing really pronounce your fabric and those can generate these very light colored myla nights and a lot of them, you can still see a relic felts bars and i'm approaching kind of a blast a mile and I classification.
Randy Kath: But other rocks some of our biotech nice's those are probably the protocol is for the blackmail nights, but these have been crushed so much under fairly high temperatures and pressures, you know under plastic conditions and not cataclysmic sites.
Randy Kath: That you can't see we've got some of the blackmail nights in the heart zone you look at them and it looks like super fine grain slate you can't even tell what they are.
Randy Kath: So we try to look back at what the problem with is the best we can, but sometimes you can't tell.
Randy Kath: But one of the characteristics of our mile in it, and I think the most mile and I it says they've got a very pronounced planar fabric to them and that planar fabric is associated with the shearing.
Josh Poole: Thanks Randy.
Josh Poole: If we don't have any more on this topic let's go ahead and move on, we have other we have other questions and people's chiming in so mark we're finally getting to you mark Carter.
Josh Poole: Go ahead ask away.
mark carter: yeah, I just wanted to say we're trying to reiterate what everybody here saying when.
mark carter: For cat nine years ago and Bart still working down there in North Carolina identify these very narrow when I say narrowly still be a coastal wide of these holly fallen Nick.
mark carter: mala night zones.
mark carter: With the problem with being or Grenada rock.
mark carter: And we still recognize that and course I moved here from the north Carolina survey mapping in the Piedmont, and we still have these narrow zones that we can put our finger on, but when I got up here the concept.
mark carter: There were a lot of folk up here who would identify say the most of the maintenance, Nice and the mutual terrain, being a hash spring mala haha strings in.
mark carter: The 1213 1415 2030 kilometers wide and places of protein through their pro tomorrow night's and they're there they have those mollinedo textures.
mark carter: You know, but at the end of the day, I think there's a distinction between those high grade.
mark carter: Whole unit mile and it was really thin or terminated zones that you can put your finger on.
mark carter: A cross country.
mark carter: that's all.
Josh Poole: Well, thank you mark.
Josh Poole: it's helpful on do we have any other any other questions.
Josh Poole: Any others brennan one of the lecturers at auburn was asking me earlier because I think he's doing a short course, right now, so he wasn't able to join into this.
Josh Poole: But he wants the field trip and he wanted to ask some questions and he asked me what the what the average particularly here in Alabama what the average defamation rate was and.
Josh Poole: asked him to elaborate on that did he mean straight rate or how fast a deformed over time or degree of monetization or what was he what was he talking about and I just walked right into his job because he asked his answer was a mile a night.
Josh Poole: it's pretty cheesy and corny but I walked right into it, I thought it was funny.
Randy Kath: Well josh if there aren't any questions, I would like to get some insight josh and I and mark we've all been looking at the heart zone as you come out of metro Atlanta down toward a band Alabama.
Randy Kath: And right around around roanoke things kind of fall apart in terms of the structure and strategic up.
Randy Kath: And I was just like to get other people's insight on what they think that regard is GM I know you've done a lot of work in the Georgia region and.
Randy Kath: You know, we Tom and I have used the key original work, you know that it's basically sc mile and I it's in a linen and we have not tie that to a strategic thing.
Randy Kath: And what we've seen with the long island we've we've mapped it over about 150 kilometer strike length and know in metro Atlanta is north of the zone of intent shearing around.
Randy Kath: whitesburg it's in the zone of intense sharing and down around to roanoke at south of the zone of content sharing and we've got good geochemical we've got three new.
Randy Kath: Zero con uranium lead dates on that, so we know it's the same unit.
Randy Kath: And then some geologists have used that as a train boundary and we don't think it is a train boundary, and so I would just like to see if we have time to open up with a little discussion about what people think of the bard and what it represents.
Jim Tull: All right, let me ask you.
Jim Tull: Randy this gym.
Jim Tull: That you know you guys have traced the long the long island Nice or the yellow dirt Nice or whatever people call it back then.
Jim Tull: All that distance what what the geometry that thing was prior to all this information, I mean that's that's a hell of us a sill if that's.
Jim Tull: I mean a lot of its semi can coordinate to the strategic feet and I guess you have to I don't know, but what do you think the original geometry was is that close to what the original geometry was.
Randy Kath: Well, Jim I think that's a great question.
Randy Kath: That, if you if you go back to some of my kagan's work and other work, it appears that the northern boundary of that is a fault.
Randy Kath: there's.
Randy Kath: It is that an intrusion and contact has been faulted I don't know but there's truncation of units along the northern boundary the southern boundary appears to be more much more concordance.
Randy Kath: Jia chemically we see a lot of variation in the G chemistry, as you approach the bard zone, the zone of intent cheering you get an increase in silicon potassium.
Randy Kath: And the strain rates go up pretty high as you get into that zone if if you mean right now, it looks like a giant sill.
Randy Kath: But if there's been a lot of displacement over a little micro fractures or micro shears and don't know how much displacements on each one of those years I don't know what it would look like, if you put it back together but it's.
Randy Kath: been intriguing when Tom Crawford and jack Madeline first started the mapping that thing and they named it yellow dirt Nice.
Randy Kath: They actually had another name field name for that they called it, the bastard Nice.
Randy Kath: And they would be you know up in metro Atlanta so almost a mile wide and you get down into the heart of the heart and it's three to 500 feet wide and it's it'd be mapping it's like there's that faster to get it so thin and persistent it just keeps going.
Randy Kath: But the Court sites do the exact same thing you know we get these court sites that are 75 feet thick and you can trace them for 10 miles and how do you do that, in a major shears.
Randy Kath: So it's.
Jim Tull: Well yeah what, what do you think the age of the of the long island creek has now.
Randy Kath: we've got three beautiful concordance.
Randy Kath: Your any my observed on dates on it to that David motor ran for me and that's for 49 to 452 but basically for.
Jim Tull: yep okay.
Jim Tull: And the other question I had for you, you got to show those.
Jim Tull: And I guess court sites you're talking about folded in the yard.
Jim Tull: Or you shows for taking your feet that's folded.
Jim Tull: very tight ice klamath falls, and then you show your sheer fabric going right through those fold hinges and you don't show any offset and that's really disturbing, if you think there's a lot of offset almost sure zones.
Randy Kath: Well, and yeah to me the shoe fabric postdates all the folds and one of the best folds that you can see, exposes up your mount Wilkinson at it, if I haven't paces ferry road.
Randy Kath: And in that area there's we've got beautiful exposures in borrow pits, and again I think if we have displacement over thousands and thousands of little micro shares.
Randy Kath: You can displace the the nose doesn't look like it's displace it's just attenuated along those shares but yeah we you can map those things gym and you can measure the sheer fabric across them.
Randy Kath: And if you saw the pictures from inside the.
Randy Kath: tunnels, the beautiful folds in the tunnels, but when you get up at the surface, all you see is the sheer foley ation over print it's very difficult to see that compositional Irene on the surface, because the weather.
Randy Kath: But.
Randy Kath: Those balls are there.
Randy Kath: You saw them in the tunnel.
Jim Tull: What I don't have a problem with that I just I just don't understand why they're not all set up, you know we can talk about your fabrics and model nights which which we all seem to know about.
Jim Tull: But the question is displacement.
Randy Kath: which we first met those.
Jim Tull: But you don't know the magnitude of the displacement vectors what i'm interested in finding out.
Jim Tull: And I don't know how you get.
Jim Tull: From just looking at you know at sc fabric, or something like that.
Jim Tull: And in your in your map you showed really well that those your fabrics cut right through those foals and they haven't disrupted the fault.
Jim Tull: which tells me there's not a lot of displacement related, even if they were displacement on micro tears, you should have this Member to hell out of those holes I would think if you had a lot of displacement on that cheers on your map.
Jim Tull: I mean that's just that's just my observation I am you probably have a better explanation, but I don't know.
Michael Thonis: Well, this violent night zone in Boston that I mentioned the one out on route 129 85 128 Sir it's it goes around Boston.
Michael Thonis: The it has been I know, several people good work in this area have suggested that there's very little actual net displacement.
Michael Thonis: What there has been it's just a lot of back and forth back and forth grinding.
Michael Thonis: And just you know you know over 10s of millions of years of grinding and and not necessarily is there, you know sound like a lot of sound like an enormous thrust it's more like to anvils.
Michael Thonis: Pushing together, and the result of that I don't know if that's kind of what you're talking about, but I think, maybe happening.
Jim Tull: yeah you know structural geologists were interested in displacements and we try to figure that out by making balanced cross sections and things like that.
Jim Tull: And so i've you know i've heard a lot about the displacements, of the inner Piedmont or things on the board, but in terms of magnitude is what is where i'd like to know how we know those magnitudes.
Jim Tull: And I you know if something's offset like on the San Andreas or something like that or the great blend you know you can you can at least measure the offset since that Pluto was in place or something like that, but.
Jim Tull: I haven't really heard a good argument for.
Jim Tull: magnitudes of displacement on the SURE zones.
Josh Poole: Well, it seems like it fits the forming the foreign plastic Lee then.
Josh Poole: Those those hard offsets they would typically see to define, you know let's say the opposite.
Josh Poole: The opposite sides of that stripes lip or the opposite sides of having one foot wall, but if they're plastic then you're attenuated things and they're they're just being stretched and attenuated into it and.
Josh Poole: These if these if the sharing, we know that the shares fractal it's happening at all scales, and so, if you take point A and point B.
Josh Poole: And you, you know you offset them brutally well, you would see that that hard displacement, but if you are taking one unit and sharing it let's let's generally say homogenous Lee along a.
Josh Poole: You know, practically and along and uncountable amount of micro shares well the tiny little micro shares with a with cumulative offset.
Josh Poole: And you could have massive offset from point A and point B now, but because the the strain and everything's attenuated you don't have necessarily heartbreak so when those old noses.
Josh Poole: There they're being stretched and pulled because they're being before classically but you may not see those you know put your nose on the outcrop or even.
Josh Poole: regionally or map scale or even you know in thin section seeing seeing actual offset planes but it's just a cumulative offset from all these micro shares.
Jim Tull: Its kind of show you.
Jim Tull: What you're saying is will never be able to figure this out.
Josh Poole: Well, if we had you know if someone were to stick to stakes in the ground a few hundred million years ago, and you know that would have been real helpful.
Josh Poole: on opposite sides of this thing.
Jim Tull: Well, you know josh your point is really well taken.
Jim Tull: But you say you know you may have all these microspheres and you may have all this huge displacement.
Jim Tull: May is one way to say it, but i'd like i'd like a number.
Jim Tull: of much displacement yeah.
Randy Kath: Right and and Jim I agree with you.
Randy Kath: I don't think it takes a lot of displacement to develop those fabrics so it doesn't have to be huge amounts of displacement to get the fabrics that we see.
Randy Kath: And you know the noses don't look displaced and attenuated that much in the long island if if it wasn't displaced and that was a tremendously large ordovician still in there.
Randy Kath: I we, I guess, I mean, given its shape that we have but yeah.
Randy Kath: We so I don't know how you quantify that are and how much does this year.
Jim Tull: A lot of there's a.
Jim Tull: lot of those courtside you're talking about have primary structures in them.
Jim Tull: And so there's primary structures haven't really been disrupted.
Josh Poole: yeah, especially the incorporate some of the jacksons gap that was something.
Josh Poole: We found is that they you know there's there's great embedding there's there's cross bedding preserved and you're thinking well how do you how would you get that around all these mile and ipads, but if you have.
Josh Poole: You know, somewhat of a hard knocker and it's just completely enshrouded by prophetic phil lights well you know graphite unnatural lubricant the final silicate.
Josh Poole: All those glide pass each other really easily so I mean you could have easily plus a defamation juxtaposed to something that's essentially in protected from it, because the strain is being.
Josh Poole: attenuated and focused through those through those founded and conduits around you know something that doesn't want to share as easily but yeah you're right like we see primaries cemetery structures.
Right.
Josh Poole: what's next anybody any takers.
Randy Kath: I started I got the discussion started on that so that's your your go josh.
Josh Poole: Yes.
mark carter: It sounds like from what I saw from your looks like from what are.
mark carter: your feelings that your board down there has a distinct photography that's different from either side of it, and as you come north, obviously, then that becomes the.
mark carter: Chakra belt in North Carolina and I would argue, actually, that regard doesn't stop there at mount areas continues on it wrapped friends or mountains and hands on up and virginia's partly is the bow and creek.
mark carter: And it could actually have two sides to it, and everything in we call up here the edmonton group would be you know what y'all are seeing down there, I just want to get your thoughts on the boulevard being a distinct.
mark carter: retainer fee that's wedged in between the eastern BLU rays and.
mark carter: Down there.
Josh Poole: Mark you're asking a question we've been asking ourselves this whole time.
Josh Poole: And that's fascinating I didn't I you know I never I haven't looked too much at the braveheart we've been up there on field trips seeing the bar through North Carolina but.
Josh Poole: I would love to see what you think might be even further extent of that but, as we, as we said in the video and as Randy said earlier that.
Josh Poole: That definitive structure, the structural zone that Lindemann you can trace that whole way once you get to roanoke Alabama it just.
Josh Poole: It just falls apart, it comes very close to the katie creek and Randy sees the katie creek or the Claremont fault through.
Josh Poole: Through Georgia and we'd send it tend to be in a general agreement that is a terrain boundary separating the de ville inner inner Piedmont island are terrain from from the margin margin.
Josh Poole: Medicine cemetery packages, but then it capsule eights this jackson's gap group and on the on the North side, the South binding we have we have the abandoned, but again.
Josh Poole: That definitive bravado seem to fall apart, so, is it hitting all of these coincidentally units and just kind of losing it's.
Josh Poole: losing its gumption I don't know if that's the right word but it wasn't being that energy that was focused in a district zone now is spread out because it's being accommodated much more easily with with these.
Josh Poole: These flights prophetic phil lights.
Josh Poole: Is it being laterally displaced to something like and paired with the Alexander city share zone where there's a lot of working hypotheses, but we haven't really pin down anything on mark Randy Dane john do you guys are Jim do you guys want to want to have more to to this fire.
Dane VanDervoort: I mean yeah just from from my experience map new album it seems to be.
Dane VanDervoort: That the zone is lift logically defined by the jacksons gap route.
Dane VanDervoort: I don't know i've gotten some.
Dane VanDervoort: Some questions for for Dr Catherine regards to his his mapping I guess it's just been rolled up East everything or in that roanoke area everything kind of falls apart, and so you know you you.
Dane VanDervoort: In your video I know you mentioned that you didn't think that the records on was all this logic boundary or a train boundary i'm sorry and I don't know if you mean like.
Dane VanDervoort: in the sense that it's internally down within the blue train or in the sense that it's Eastern blue Ridge train verse in or Piedmont train boundary.
Dane VanDervoort: Because they're sitting there from again from my experience mapping there seems to be a clear with logic contrast when you go across the katy Perry, you know you're getting away from those graphic shifts into.
Dane VanDervoort: into the lights and the falsehood.
Randy Kath: They indicate advocated creek fault it's got danville and it's hanging wall and we've got three tunnels that tunnel across the katie couric boundary.
Randy Kath: So that is, that is, the train boundary but the bird zone.
Randy Kath: is not part of the katie couric structure.
Randy Kath: The bard zone is it has its own unique mythologies.
Randy Kath: down in Alabama you you equate that with jackson's gap, but if you go back to the key so original interpretation it's it's not a little logic package that defines the bar.
Randy Kath: it's a sentiment and sharing that's what defines it is just so happens down there because you're jackson's gaps wrapped around the tallahassee same form, but the southwest end of the Board appears to peter out go on Echelon into the Alexander city, it is a structure it's not a strategic.
Randy Kath: Yes, I think you got to go back to the original work by key and a lot of the work that's been done on the card is it's really a structure and a topographical intimate.
Randy Kath: And as you come up in metro Atlanta, it leaves the jacksons gap like stratego up.
Randy Kath: And we get these own fields part nice's and lots of em big and people lights and other mythologies that aren't characteristic of the jacksons gap so to me it's a structure that over princess photography and it is not related to the katie couric.
Claremont fall.
Dane VanDervoort: And then again that's just kind of my limited experience you know I haven't seen a lot of those rocks.
Randy Kath: In Georgia, if I put the train boundary i'd put it at the katie couric Claremont fault.
Randy Kath: Because you've got day bill complex thrust over the mythologies and over the yard and.
Randy Kath: When we tunnel through in the Atlanta usc so tunnel, which is a 28 foot diameter tunnel had beautiful exposures.
Randy Kath: And the football the katie couric fall is about 500 feet of defamation and as soon as you cross that fall, there is not a lick of regards here, Patrick at all, and the end the day bill or the Claremont milan's has its we have here in Georgia very stressed over the top.
Randy Kath: And we may drill through that as well.
Jim Tull: hey, let me just Dan Dan, can I ask a question.
Dane VanDervoort: Yes, are for sure.
Jim Tull: You know the in Tom knows these guys really well bentley and every.
Jim Tull: You know, do a lot of really foundational work all over Alabama Georgia.
Jim Tull: Yes, and they they're the ones that define excellence get group course, but just just along what you were just saying Randy.
Jim Tull: Things breaking down at it roanoke.
Jim Tull: One thing that doesn't break down and roanoke is the Court sites.
Jim Tull: Has courtside continue right through their own Eastern West quad you find them in the phone the quad well developed that Tom Crawford worked on.
Jim Tull: So that's.
Jim Tull: That would be jackson's.
Jim Tull: Gaps photography as originally defined you know I think they call it the backbone courtside or whatever was down towards tella tell senior.
Jim Tull: Had taxes yeah but anyway those and and you know some of mark students have pointed this out really well those court sites are really distinctive marker units that we can trace completely around the day bill complex.
Jim Tull: into Georgia we've been mapping in Georgia, following that stonewall on up towards Lithuania.
Jim Tull: And so you know, there is a stepping up, and I think if you look at the students at marks had working on some of our zone, maybe, including you josh I don't remember where you work but.
Jim Tull: You guys all mapped good strategic up in the zone.
Josh Poole: yeah.
Jim Tull: same thing for you like you said yes of course sites so forth, and they're traceable, for a long distances they're not shared out.
Randy Kath: But yeah I agree there is a particular free but, as you come along strike that topographic ligament and sheer fabric cuts different strategic.
Randy Kath: So it does the does the sheer fabric wrapped around the tallahassee Sim form with the Court sites that would be the question I have, and I think there's no Absolutely not.
Jim Tull: So you've got you've got that I mean taken originally defined the palisade.
Jim Tull: way up to the north area, so those court sites can be traced all the way from the SLIM of the.
Jim Tull: Of the Tennessee same form, all the way around the hinge.
Jim Tull: And then, all the way down and.
Randy Kath: I will.
Jim Tull: trigger fee that most people have accepted, starting with Tony and Bob bentley and definition.
Randy Kath: And I would like us to say yes, that is part of the jacksons gaps or tigger thing.
Randy Kath: But not the braveheart fabric cuts the jacksons gap strategically, so I think that's one of the problems we have in the literature right now is a lot of the early workers didn't have the data that we have and anti agree the Jackson gaps photography wraps around.
Jim Tull: I feel sorry for any students just starting to work on the rewards on and trust away through.
Jim Tull: The literature.
Randy Kath: It is a math.
Josh Poole: ever growing a culture but.
Randy Kath: I think that's where.
Randy Kath: We gotta do we gotta agree at some point, all of us, what is the bird is it a structure is that the strategic.
Randy Kath: And to me it's one of those two and if we define it as a strategic up then we've got to go against what Keith originally said and that's fine we don't have to honor the old literature, but in 1905 he defined it.
Randy Kath: So I think the first thing we have to do to understand what this is is define least agree on what we're going to call it is jackson's gaps particular fear for the sheer fabric and the Lindemann.
Josh Poole: i'd like to hear.
Josh Poole: don't pull chime in but I completely agree with you Randy and and Jim yeah it's it, I think I think the problem we see is that.
Josh Poole: And I know we've all independently.
Josh Poole: amongst ourselves talked to this until we're all you know we're exhausted, but that definitive structure of the reward.
Josh Poole: At roanoke scenes tension is fall apart, and it goes into the jacksons gap group and then that's where we're.
Josh Poole: we're seeing that look like encapsulates the Jackson characters and you and you all are yeah that that wraps around the test is informed goes on up into Georgia on either side of that limb, but.
Josh Poole: I think that's, the problem is that the structure itself that definitive structure seems seems to I don't know if it just Peters out or is.
Josh Poole: Just accommodated in a more distributed zone.
Josh Poole: Still bold do you want to add more to this week so just just a heads up, we have seven minutes I think they're going to kick us out on the hour, so if you do have questions or comments or want to chime in feel free to just want to throw that out there, so okay.
STELTMG: Well, the only thing I would add.
STELTMG: I agree with what you said earlier about the the sharing and the billboards and what we see there at jacksons gap and the railroad tracks action it's it's all tied up in the.
STELTMG: The basic units and philanthropic prophetic units and do you ride their primary structures that are preserved and they're beautiful.
STELTMG: they're beautiful cobalts in some of those rocks i've shown those some need some DS GSA presentations are it's all manual conglomerates and their cross events and things that you mentioned stuff.
STELTMG: That the shears running around there luckily I run into men I think you've all probably seen these phonetic court sites that those things will show all sorts of defamation in terms of kink kinks folds and things like that, and some beautiful structures and knows.
STELTMG: The katie couric fault.
STELTMG: Maybe Randy can comment.
STELTMG: On that and.
STELTMG: That up in Georgia, but in Alabama I think that's an earlier structure, I think that that structure wraps around the fallacies informed along.
STELTMG: With that jackson's get groups photography and I think that that structure the katie couric becomes the stonewall line when you wrap around the other.
STELTMG: The the hinge of the totality sinful I haven't mapped that boundary you know i've been to George I know Jim and some of your students have been working on that boundary of them, what do you think of that stonewall line up there.
Jim Tull: Are you talking about the the katie couric or the stonewall.
STELTMG: The stonewall.
Jim Tull: yeah you know mark.
Jim Tull: i'm beginning to think those are actually different faults.
Jim Tull: The stonewall is actually intruded by the lake granites.
Jim Tull: They cut across the canola and.
Jim Tull: stone mountain I think cuts a stone wall and yet, those same grants are shared apart like Tom Crawford has shown in some in Higgins on against the katie creek or against the boulevard zone.
Jim Tull: So I think that there's motion on the katie couric that postdates that stone wall and I actually think the stone wall is locally overturned by.
Jim Tull: map scale falls in Georgia.
Jim Tull: So you know and that's a puzzlement to me because you know what the katie couric has you know right lateral slip on it, I don't once again I don't know how much but.
Jim Tull: What happens to him when it comes south.
Jim Tull: You know, following the trend of the band default and then supposedly linking into the stonewall I think that's a problem, we need to discuss.
Jim Tull: Exactly how those two faults relate, I thought for a long time, like you just said that those stonewalling this katie creek or the same fault, but now i'm beginning to think that they're kind of magically separated and they're separated by intrusions in those.
Jim Tull: Those late granites that is.
Jim Tull: What Tom what's the name of those other grants there against the billboards on.
Jim Tull: The link right there sure.
Randy Kath: to grab at.
Randy Kath: The Ben hill yeah.
Jim Tull: yeah yeah.
Jim Tull: Those two grants.
STELTMG: yeah that's on the West.
Jim Tull: don't you.
Jim Tull: Think they're cut by the Claremont phone.
Jim Tull: calling me creek.
Randy Kath: Now, Tom says yes, I say no.
Randy Kath: So if you if you look at the Ben hill.
Randy Kath: The band the hills appears doing true to cross the katie couric fall the power matter it streaked out along mutating creek.
Randy Kath: Bam hill cuts across it.
Randy Kath: And we can map it it cuts the mile and it cuts the.
Randy Kath: fall down yeah but the palmetto it's.
Jim Tull: mapping you guys have done up there, shows that those were cheered up against you provided, I mean i'm looking looked at Higgins work and tom's work, I thought they were pretty well convinced that they they the Labor movement on the east boundary that hard cut those grants Tom the right.
Josh Poole: We have a problem in West Georgia i'm sorry about that.
Josh Poole: We have about two minutes left that's according to my computer clock which I don't know if that's the same as their system clock, which is a registered.
Josh Poole: reminder when it just kind of.
Josh Poole: Clearing up.
Josh Poole: we've been talking about very specific structures and very specific.
Randy Kath: units and.
Josh Poole: Oh you're talking about.
Josh Poole: or certain mile kinetic the particular searches were talking about are very specific discrete zones of defamation, so all of this year, and a lot of them represent beautiful St fabrics.
Josh Poole: role garnets a Sigma delta tales asymmetric folds all that beautiful the whole gamut of of sheer structures, but we do see these very discreet zones and that's those discrete zones are what we're trying to ultimately define and.
Josh Poole: also largely defamation zones, so if we can can totally continue this conversation until they until they kick us out I don't really know how the ending of this.
Josh Poole: is handled, oh no, they just end it or if they politely eases off of it, but we can totally continue the conversation has to remind everyone of that, and if we have any other comments or questions you last chance.
Randy Kath: hey josh can I share my screen for a second.
Yes.
Randy Kath: I don't know I can't see if it shared on.
Josh Poole: yeah.
Randy Kath: I see it, what do you see.
STELTMG: that's like the.
Big.
Randy Kath: Ben hill.
Randy Kath: So here's the katie creek fall coming up here.
Randy Kath: chopping off all these units and then the band hill comes across and cuts the katie couric fault, right here, you can take this up on the ableton Claude.
Randy Kath: i'll zoom out just a little bit So you can see the edge of it so here's the katie couric fall term enough here.
Randy Kath: truncated all these units and then, when it gets up to the band hill the band hill cuts across it intrudes into the button shifts in the regard.
Jim Tull: So you're telling me now the been hill postdates to sharing Is that correct.
Randy Kath: that's what I think.
Jim Tull: that's what I that's what I thought and that's what I thought Tom said.
Josh Poole: about something maybe.
Josh Poole: So any any final parting words or comments so Paul do you want to do you want to.
Josh Poole: grandstand or anything or anyone want to add.
STELTMG: I just want to thank everyone for being here, I see a lot of names I don't see the faces, it would be nice to see some of those faces.
STELTMG: But I just want to thank everybody for for being here yeah it's good to do some names I haven't seen for for a long time, I appreciate that and i'm glad that we're doing this remotely because we have a storm run into offering right now, since probably offer the better.
STELTMG: But i'm gonna have to sign off and it's it's three now i'm gonna have to sign off because I have to go pick up my granddaughter she's that.
STELTMG: she's at daycare right now and i'm going to be punished if I don't get to do that again, I appreciate all all of y'all what you've done for me it's good to see y'all and y'all enjoyed meeting.
Josh Poole: yeah Thank you all for joining us if you have we can we continue further discussion on if you want to email us, I think our contact email or contact us somewhere.
Josh Poole: it's somewhere out in the ether, but um if you want to get in touch with us, or have further questions or want to just talk more feel free that's what we're here for, and thank you all for joining in on this.
Jim Tull: audrey audrey if you're gonna level fine you need to level it to the convenience instead of participants okay.
RISE GSA Audrey Heun: got it yeah.
Jim Tull: I just running over.
RISE GSA Audrey Heun: For a GSA representative that this is a great experience planning this field trip with Dane and josh and.
RISE GSA Audrey Heun: Randy and john and bill, I think I got you all so really great job it's great seeing all these field trips come together on the online format and.
RISE GSA Audrey Heun: We didn't really know what we were going to get when we kind of.
RISE GSA Audrey Heun: said hey, these are all going to be online and each of the field trips have done something a little different so we really.
RISE GSA Audrey Heun: appreciate you guys still going out in the field and and taking the time to make that video and and share with us, because now we can archive it and continue to share it so.
RISE GSA Audrey Heun: You know if you haven't it sounds like a lot of people were able to watch it but it's going to be up on.
RISE GSA Audrey Heun: This meeting platform for a year and then we're trying to figure out exactly where will our archive it within for GSA members so.
RISE GSA Audrey Heun: All their contact information is on the southeast website under the field trip tab if you want to bother all these guys a little bit more and continue the conversation, but really great job and really appreciate it was nice working with all of you and planning this Thank you again.
Dane VanDervoort: Thank you.
STELTMG: Michelle i'm looking forward to seeing the field trip i've seen it yet so.
STELTMG: i'll take care.
Josh Poole: Oh, it doesn't surprise.
STELTMG: yeah I oh.
Josh Poole: Thank you.
RISE GSA Audrey Heun: Thank you.
Dane VanDervoort: yeah and.
RISE GSA Audrey Heun: Everybody left.
Dane VanDervoort: I was just saying you know there's a big push from the usgs to help on shore up some the state line issues and that's definitely something we're gonna have to work with brandi and Dr toll and in.
Dane VanDervoort: Tom Crawford I guess help clarify some stuff but.
Dane VanDervoort: that's further down the road I guess at some point.
Josh Poole: Well Randy Randy just popped in.
Josh Poole: But he's talking but.
mark carter: hey Dana i'm here you're getting geophysics down there.
Dane VanDervoort: yeah that's what they're telling us that's what we are morning here in the next year, so.
Dane VanDervoort: we're looking forward, hopefully that'll help clarify some issues you have a new fiscal survey with fema.
mark carter: So I think it will be.
Very he'll.
mark carter: Certainly, certainly the data that he shown us up here looks looks really good and, of course, the South Carolina data set amazing so.
mark carter: Thank you all, would be able to do the job Arthur and I still want to come down there and.
Dane VanDervoort: Show us around for a couple of things at some point time when we can finally get back out would for sure it's opened by anytime you guys get a chance to come down.
Dane VanDervoort: we'd love to have you.
yeah.
Dane VanDervoort: But.
Dane VanDervoort: But no, was it says, Dr pat we're um you know there's a big push from the usgs to clarify something stateline issues.
Dane VanDervoort: That kind of ties directly into this we're gonna have to you know work with you guys to help kind of clarify some of these issues.
Josh Poole: piggybacking off that day.
Josh Poole: We Randy and mark and I actually met.
Josh Poole: A couple weeks ago and kind of where we have planned a big trip across the whole bar, but we only got to do, half of it.
Josh Poole: And so we're we're working on currently merging our big compilation map with randy's we've been trying to do this for years, we just haven't got around to it um I don't know mark has reached out to you, but he has some unfinished quads that he needs digitize and he just doesn't do.
Dane VanDervoort: I know I mean I know he's got his death as as mapping from roanoke West and Davidson that needs to be.
Josh Poole: If you were hoping that he might can maybe reach out to either you or me but likely you to help if you have time to ditch.
Dane VanDervoort: yeah.
Dane VanDervoort: We might can.
Josh Poole: Go to our map and you know start yeah.
Dane VanDervoort: For sure it's you know, like i'm Dr Kathy has his mapping and then.
Dane VanDervoort: Who has mapping a little further, and they are a little further north and east from blue Ridge and stuff so.
Dane VanDervoort: yeah yeah you're.
Josh Poole: Right between randy's northern stuff and then his stuff so.
Dane VanDervoort: Exactly exactly So hopefully.
Josh Poole: We need to clean this up, though.
Dane VanDervoort: For sure.
Dane VanDervoort: For sure so.
Randy Kath: I like stateline palms.
Dane VanDervoort: he's busy I guess.
Randy Kath: You get gives us something to do when we're having a beverage josh.
Josh Poole: Right yeah these napkin drawings, we do.
Randy Kath: a pretty good drawing pseudo that's right.
yeah.
Dane VanDervoort: Okay well that's I appreciate it josh again.
Josh Poole: yeah, thank you for all the help I appreciate all y'all for everything, so thank you.
Randy Kath: I think such a good job, everybody.
mark carter: Very good job.
Josh Poole: Thank you, I appreciate it, thank you all.
Dane VanDervoort: See ya.
