Calcarenites in 12 and 13 have flat top brown siliceous stained.
PG. 132
14) Conglomerate, about 6" grading up into a rubble of algal, sponge, a few fusulines which may have been transported, crinoid stems, 6'.
15) Sandstone, light brown 1/16" to 1/2" beds - 7'.
16) Limestone, calcarenite, with organic frag. granule size, 1'.
17) Sandstone brown - 6".
note: here the calcarenite is irregular at its base and rests on eroded and weathered brown sandstone - (apparently the major break in sedimentation?)
18) Like #16, 2'.
19) Limestone, biohermal, gray weathering with brown conglomerate chert pebbles.
7/22/57/7, 6' becomes a calcarenite at the top (2') and a flat top surface with siliceous iron (brown) weathering.
PG. 133
20) Sandstone, brown, like #15 - 4.5'.
21) Limestone, rubble, with chert conglomerate and limestone conglomerate cobbles: grades into a calcarenite (upper 6" to 1') with a flat, siliceous iron stained upper surface. Collection 7/22/57/9, 7.5'.
22) Sandstone, light brown weathering, much coarse calcite sand with the fine quartz sand. 2'.
23) Limestone, massive, brownish-gray weathering chert pebbles, and limestone boulders scattered in this. 15'.
24) Limestone, mostly calcarenite - 4 cycles of rubble through calcarenite to flat top with siliceous Iron stained; 21'; (at top 7/22/57/8) top of ridge.
50' northeast of measured section a chert and quartzite conglomerate has cut a 8' channel in unit #25. This conglomerate appears very much like unit 8 (in the lower part).
PG. 134
The conglomerate intervals 1 through 8, thicken northeast ward toward the old Decie dry hole. This is accomplished by a slight thickening of individual beds in that direction, but also by off lap in what are apparently large channel bedding.

Section 8 -
Wolfcamp over lies Gaptank angular unconformity. Gaptank strike N75W dip 9° NE.
Collection 7/22/57/10 and 7/22/57/11 in Gaptank at this point.
1) Limestone yellow weathering, yellow is from a high % of silt, shot through with Calcite veins 7/22/57/10; 30'; covered below.
