"Accordingly there was no mountain making here at the close of the Pennsylvanian. The question now arises why is the Tensas or much more deformed than the later Pennsylvanian and Permian? Can the angular unconformity that I saw last Sunday be actually an angular unconformity. If so the Tensas should be Cretaceous, and the deformation post-Cretaceous. Does the Tensas = Starley-Jackson? Then at some time in the Pennsylvanian the sea again flowed into and over these Cretaceous strata making the unconformity and uplifting them. Just as the later Pennsylvanian in all = Canyon and Chico. Then a complete break followed by the Permian deposits that have a relative thickness of 6000 feet. Wolfcamp is upper Cretaceous Cretaceous is late Pennsylvanian"
