9) Alteration of Calcarenites and brown gray shale, Calcarenites become very fine pebble conglomerate higher in unit; 55' to 60' interval is badly covered. 10) Covered, 40' to base of Section 13a unit #1. PG. 95 {note: illustration: Section 13b: bed 8: Collection 7/12/57/3 bed 1: 7/12/57/1 bed 3: 7/12/57/2} PG. 96 {note: illustration: Conolyn Brooks Ranch: see illustration for notes} PG. 97 Section 34 (part) Section 14, 3/8 mile west of C. Brooks Ranch House. Covered below 1) Sandstone, light orange-brown weathering. CaCO3 cement in part, a few grains of calcite 6" to 2' to 3' beds - 38'. (see unit 7 Section 13b). 2) Shale, gray to brown with 2 beds (1') like #1. 17'. 3) Limestone silty and sandy, but abundant fusulines weathers light tan or yellow. Brach shells also abundant. In 3" to 6" bed, uneven bedding surfaces. 29'. 7/11/57/4 NO! 7/28/58/1 check samples 7/12/57/4 4) Covered, 55': If other side of gully is compared, this interval is a massive calcarenite, gray weathering with indistinct 6" to 6' beds. It caps that ridge but not the one the section climbs. (Fault?) 5) Limestone, gray mottled colors, darker "pebbles?" in a lighter matrix; 1.5' to 3" beds irregular bedding planes 18'. PG. 98 6) Limestone gray massive, 44' crinoid fragments, brachiopod shells. 7) "Hess" Conglomerate 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 #6 and the "Hess" Conglomerate, but it is within the 10'. Along the front of the central segment of the Brooks Ranch Wolfcamp ridge most of the drains are the result of erosion in the zones of weaknesses caused by faulting. These faults have throws of 10' to 50'. The limestone ledges back of the ridge have several zones of slicken sides which I interpret as movement on bedding planes as the Wolfcamp limestone was arched during later. Marathon basin movement. Probably past K all though I have no direct evidence for the time of movement. The faulting perpendicular to strike cuts the Hess and
