6) LS, gray massive, 44" crinoid fragments, brachiopod shells. 7) "Hess Congs. about 10' above this last unit (6). This is on a dip slope so it is difficult to set the interval between the top of (5) & the "Hess" congls, but it < within the 10' Along the front of the central segment of the Brooks Ranch wolfcamp ridge most of the draws are the result of erosion on the zone of weakness caused by faulting. These faults have throws of 10'-50'. The LS ridges back of the ridge have several zones of slickensides which I interpret as movement on bedding planes as the wolfcamp ls was deched during Late(?) Marathon basin movement. Probably post K although I have no direct evidence for the time of movement.. The faulting perpendicular to strike cuts the Hess & Leonard so that it aids in draw forming here also. The remnants of K caps are apparently protected by differential movement on Sect. 14 7/12/57/14 7/11/57/14 These faults and can be explained in this manner. The evidence in section 13 suggests that the Goptank & the wolfcamp, limestones either converged and form a combined mass of LS, or that the wolfcamp is locking. The study of sect. 14 indicates this is not to be taken at first meets the eye. I believe, based only on lithology, that unit 3 of section 14 is the same unit as #1g section 13a. The #1"c ledge section 14 are probably the same as bed ?% 13b. The #8 ledge of 13b may
