ENNING - STONEVILLE AREA with Pethyjohn. Divisions of Fox Hills Lower part, below coals, interbedded, loc. bedded f.g. sand + sh. + sandy sh. some x-bedding. He has beculite - prob. clinolobatus 50' from his basal contact & we found crushed large-ribbed form prob. grandis below this. Pethyjohn puts contact at point where grdztrznzl sequence becomes predominantly sand. Coal beds - a thin bedded sequence that seems to be related to lower FH, rather than beds above. Upper part - locally white uncemented ss with wraith pyrite bells and CaCO3 indurated ledges over lies coal. Also locally there is unit of pink + rzvricolored shale with ss ledges underlying White River sand apparently overlying coal horizon. Problem is relation of the "colored beds" to the sand overlying coal. Possibilities 1. SS and colored beds facies same units SEE p. 37 --> 1A Upper Fox Hills 1B Post Cretaceous 2. Colored facies pre-White River wraith. Fox Hills. (Agnew) 3. Colored facies different + younger unit than ss, and cut into it. (Pethyjohn)
