CRATON SEDIMENTATION OF FERN GLEN FROM KENTUCKY TO ALBERTA
Three ocherous cycles above the silty Rosalea unit of Fern Glen were traced from Bowden West Virginia thru House Springs, MO to Cadomin Alberta. At Cadomin cycle 1 is 12" thick, cycle 2 8", and cycle 3- 4". At House Springs cycle is 11", cycle 2-10" cycle 3- 4". At Bouden cycle 1 is 2'6", cycle 2 is 15", and cycle 3 is 15". At the top and base of each cycle is a thin white marker. Between the ocherous beds are black silty beds from a glacial period.
Fossiliferous ocherous beds were formed during warm reducing periods. Shorter cycles (4"'s) are present thoughout all.
