Tribal funds. The significance of other letter designations
used is less clear. The third part is an accession number
for
that
district,
representing
the
order
in
which
the
wells
are drilled. Tn addition to the well number, the townshiprange location, total well depth, sampled interval, probable
aquifer, and pages covered by the description are also given.
Table 1 may be used in 2 ways:
1) to determine the
availability of sample descriptions for a specific well
of
interest and 2 ) to determine the identity
of
wells
for
which
there are samplesor sample descriptions in a general area
of interest. Tn the first case, look for the well in Table
1 using the BTA field number. If it is listed, a sample
description is included in this report and cuttings
on are
file in the Bureau. In the second case, consult Table
1
for the area of interest using county, township-range, or
B1.A district number (fig.1).
Samples and sample descriptions
axe available for all wells listed.
EXPZANATLON OF DESCRIPTIONS
The
descriptions
which
follow
were
made
by
conventional
study o f the cuttings with a binocular microscope. Abundance
and
textural
characteristics
are
based
on
visual
estimates
following Terry and Chilingar(1958) and Powers (1953).
All qbbreviations used are defined in the to
"Key
Symbols and
Terms!' (p. 24).
Each description includes the following

The specific descriptive information given after the
general lithologic term(s) varies slightly with rock types;
for clarity, this information
is always presented in the same
order as follows:
SANDSTONES -- color; texture (grain size, grain
sorting, grain shape); mineralogy; matrix, cement,
induration; miscellaneous constituents or
characteristics.
CLAYEY OR SILTY SANDSTONES -- color; texture (of
sand); general commenton clay or silt; mineralogy;
matrix, cement, induration; miscellaneous constituents or characteristics.
OR SILTSTONE -- color; general
SHALE, SILTY SHALE,
comment on silt or sand (if pr,esent); cement,
induration; miscellaneous constituents
or characteristics.
SANDY SILTSTONE OR SANDY SHALE
-- color; texture of
sand grains; mineralogy.of sand grains; cement,
indur,ati.on; miscellaneous constituents or
characteristics.
The rock color chart prepared by Goddard and others
(1948)
and distributed by the Geological Society of America (GSA) was
used for rock color des2gnations. In several~casesidentical
names are givenon the chart for two sightly different colors
such
that
name
alone
cannot
be
used
without
creating
doubt
to the color intended. Three cases of such duplicate color
designations
report:
were
encountered
in
samples
covered
by
this
, and "moderate red".
"light brown", "yellowish gray"
As used here these terms refer to colors 5YR6/4,
5Y7/2, and
5R4/6 on the chart, respectively. All other color designations
e
follow
the
GSA
chart
exactly.
