429. Coeval Miocene Magmatism and Crustal Extension in the Colorado River and Death Valley Extensional Terrains
|
| Primary Leader: J.P. Calzia |
| Leader(s): S.D. Luddington, O. Tapani Rämö, C.F. Miller |
| Field Trip Description: Geologic, petrologic, and isotopic studies of Miocene plutonic and volcanic rocks in the Colorado River and Death Valley extensional terrains demonstrate a close temporal and spatial relation between magmatism and crustal extension; the coeval nature of the magmatic rocks and extensional structures suggest a genetic and possibly a dynamic relation between these geologic processes. This four day post meeting trip will begin and end in Las Vegas, NV; field evidence and lab data presented during this trip will be summarized into a magmatic-tectonic model that relates magmatism to coeval crustal extension in extensional terrains.This field trip includes a visit to collect the Precambrian alkalic suite (including shonkinite, syenite and carbonatite) at Mountain Pass, CA. |
| Field Trip will span: 3 days |
