Section 23, ½ mile S. Allison Ranch.
Being section not affected. Dip 35°, N45W.
1) Calcite, dark orange-brown, quartz,
rich near top. Crystalline frags common.
1'
Some wood frags.
2) Covered, 105'. There seems to be a few quartz
and calcite, and rubble (s?), but mostly
shale in this interval Coll. 8/3/57/1 at top
3) Organic frag s., major orange-brown near base.
Light brown lighter, in bed 6' to 1', 1'/62'
light gray shale interbeds. 44'
Coll. 8/3/57/2 near tan
4) Covered 25'
5) Conglo.; light gray, microls calcite here.
almost pure calcareous small
buildings up to 10" diam. Coll. 8/3/57/3
8' affected; one pebble or cobble
this collect has garnetines and seems to
be related to the organic frag s "3 (which
is definitely present in this core)
8/4/57 Dougout 14th.
1-21/
Coll. 8/4/57/1 - Above rubble and sample in well bedded
Ness Ls; This beds helps form New dip slope of the
hills are set extent of Dougout Mtn. Thin to
from the SW and along 2½ miles NNE of the SE end of Mt.
Coll. 8/4/57/2 - From near ground cover on
wolfcamp Conglo. Slope. There is some concrete
tank on top grade of long ridge extending NE
of Dougout 21st; no other source for these
fragment obvious, I would to be from wolfcamp.
Coll. 8/4/57/3 - near base of wolfcamp slope
and near gap tank (?) contact with wolfcamp.
The lower most Wolfcamp Conglo here is a
breccia of clast fragments with siliceous
cemented cement. I would like to suggest
this represents the uncutched (unexposed?)
thrust sheet breccia and it served as a
gravel source to prevent over the smoothly
surface of the truncated and folded gap tank.
Silica & hematite (calcretic times?) combined
to cement the concrete parts together of the
wolfcamp formation as well as our interjected).
This might help explain some of the breccias
on the Dece Ranch.
