(26) 8/10/57 Black Peak [king's]?? sect. 28 Bk Peak on S side see King (930), p. 121 who examined My notes are made from the north side 8/10/57/1 - ls float from ocean maximum peak 8/10/57/2 - from very dark gray feld l.s. at top g f low lying ridge just at heart of key Black Pk X-section xx Loc. 57. Loc. 60. NW 8/10/57/2 8/10/57/1 8/10/57/3 gap tank's? covered thrust fault John Miner says this is Band of Taylorsville in age, any 29/57 (5) (4) (3) (2) (1) 1) Ls, most dark gray, some mottled pattern in the strata; fossils coarse, a few coral + crink columns; about 90'; Coll. 8/10/57/1 2) Covered, 40'; Instream cut, some badly shattered & fractured "shale" which is mostly green siltstone and green brown sandstones (weathering red brown). These seem to be similar in lithology to parts of the Haywood and parts of the gap tank near August Mt. (27) 3) Shales, black, organic, with some vitre. 1/8" to 1/4" bedding; a few sandy zones or beds; 60'; the sandy zones weather red brown. Coll. 8/10/57/3 (Thrown out) 4) Ls, very dark gray to black limestone, some bedding surfaces are silicified with a brownish colored material; -beds 1"- to 2"; 40' Coll. 8/10/57/2 5) Covered above. The color and general lithology accords me of the Heeco origin from Woodruff's area in the Eagle Mts. These shales are more organic, but the aggregate % are roughly similar. The Black Peak area has been faulted and deitated badly so that while these figures are only approximate, I would judge these are minimum figures rather than maximum. The little fossils from 8/10/57/2 are like some I've seen before. They are larger than the Schizostella's and appear to be Graptolites from field experience. The rock facies here seem to be quite strange for this part of the west Texas region.
