Grenad siliceres, digyranus and juruline. 14-1/2' 8/21/57/2 10) Shale, siltstone, + v.f. sandstones; light brown weathering. 17' 11) Covered, 21' 12) Massive LS, light gray to light tan weathering. lower 6'-10' have large LS cobbles, small amount of fine chert pebbles.

[no thesis sec. #] [see p. 129 Nb.2] gap-tank below is badly folded + faulted, chert congl. breccia in the greenish chert, beds of chert below seem to well bedded and not extremely broken - gap-tank is represented as well as brown sandstones. 1) Congl., much chert and limestone cobbles. brecca cemento matrix. dips about 15&N; 20' become fine upwards, some organic fragmental material comes in. 2'-3' beds. 8/12/57/4 2) LS, mid-gray, nearly organic frags., some small chert pebbles. Crinoid stems dominant. haz fernish line (weathered), Coll 8/2/57/5 about 20' up from base. Coll. 8/12/57/6 about 60' up from base- thickness - 78'+ The upper beds dips about 45 to 60°, I suspect this unit is faulted Leonard, a thin litg. upper here is #1 and no lower Ners or Wolfcamp at all.
