Includes fossils?Y
Lithology description: "red-mottled micaceous arkose" "red shale and coarse-grained stream channel sand" (Berman, 1977)
Environment:fluvial indet. Tectonic setting:non-subsiding area
Geology comments: "relative abundance of micaceous and coarse arkosic detritus often associated with the bone-beds suggest that these Abo sediments were laid down nearer their source and under conditions of better regional drainage than contemporary "deltaic" Wichita rocks in Texas. The late Pennsylvanian and early Permian uplifts of the near-by "Ancestral Rockies" were evidently responsible for this early advent of red-bed deposition on the west side of the Permian Basin..."
