112 There is almost no ls in this cong, but it still seems to be the "new" cong as on other side ls buildup cobbles as high as 70%. #20 In the stream draw outcrop 20 is exposed. Calcareous shale siltstone, rich fauna fossils in verpe wash. Collection 7/17/57/9. white to light cream weathering. Becomes more calcareous and grades 2-3 into marry sidded lime to biheral sly, 35'-40' The #14 "SL"s of King's Gap tank appear to have beginnings in the "Liddlewhite" zone just to the west of gap tank. I find no field evidence which would assign a wogcamp age to King's belts in this area. But it is not until we get above that extent that we find a distinct break in lithology. 1/18/57- East of Texas Highway 51, beds of what I believe are wogcampian age (at least lithology) are folded and faulted quite boldly. The area's a syncline strikes N74W from peaky Kn or NW taking back up a valley in K on St side y road. Slides read 7-18-57-11 7/18/57/1 is from a sandstone in the creek in this syncline. This syncline is probably dup resulting from folding NE of locality 7/18/57/1 50 yds NE of locality 7/18/57/1, beds are one end; probably another fault not exposed. These structures predale K although the K was folded or even faulted (1' throw) in this zone of weakness. This little area is very complex - 2 sets of faults; one N74W axis and one N36SE.
