DESCRIPTION OF UNITS
ALLUVIUM (Holocene) Clay, silt, sand, and gravel in channels and on flood plains of modern
streams. Includes terrace deposits of similar composition located directly above and adjacent to
modern channels and flood plains. Thickness: 0 to about 30 ft
ALLUVIUM OF NORTH CANADIAN RIVER (Holocene) Clay, silt, sand, and gravel in channels and
on modern flood plain of North Canadian River. Area probably subject to frequent flooding.
Thickness: generally 0 to about 40 ft, rarely over 40 ft
ALLUVIUM OF NORTH CANADIAN RIVER (Holocene) Clay, silt, sand, and gravel on Recent flood
plain of North Canadian River about 5-10 ft above Qacy. Area rarely subject to flooding. Thickness:
unknown, possibly as much as 50 ft
REMNANTS OF OLDER TERRACE DEPOSITS (Holocene and Pleistocene(?)) Clay, silt, sand,
and some gravel adjacent to the flood plain of the North Canadian River. Sand commonly is medium-to
coarse-grained and very light colored; when present, gravel locally consists of concentrations of
distally derived pebbles and cobbles, mostly subrounded quartz and quartzite. Base of unit is about
0-100 ft above the modern flood plain of North Canadian River and ranges in elevation from 1030 ft
above sea level on the west side of quad to 1200 ft above sea level on east side of quad. The top of the
unit is as much as 110 ft above the modern flood plain and is as high as 1220 ft above sea level.
Thickness: 0 to 80 ft
REMNANTS OF TERRACE DEPOSITS (Holocene and Pleistocene(?)) Concentrations of distally
derived sediment, mostly very light colored, subrounded quartz grains, with minor quartzite pebbles;
sand may also exhibit re-working by aeolian processes into distinct dune structures; base of deposits
more that 50 ft above modern flood plains. May represent former course of North Canadian River or
eroded re-deposited Pleistocene gravel similar to Qgco. Thickness: 0 to about 20 ft
GARBER FORMATION (Permian) Sandstone, mostly fine-grained to less commonly very fine to
medium-fine-grained; appears to be very fine grained near base; moderate reddish brown (10R4/6),
moderate reddish orange (10R6/6), moderate red (5R5/4), light brown (5YR5/6), and dark yellowish
orange (10YR6/6); sandstone- and siltstone-pebble conglomerate, siltstone, and shale are rare.
Sandstone typically porous and friable. Commonly weathers to smooth, rounded outcrops; locally
with platy to flaggy to rarely slabby appearance. Locally weathers to hard, dark-colored (grayish
black [N2]) beds completely cemented with hematite, calcite, and/or silica. Dark-colored sandstone
blocks locally form lag deposit over weathered outcrops. Large- and small-scale crossbeds, trough
crossbeds common; many outcrops characterized by inclined beds and channelform deposits,
although plane-parallel stratification also present. Sandstone locally color-banded (e.g., moderate
reddish brown (10R4/6), grayish red purple (5RP4/2), and grayish yellow green (5GY7/2)) or with
mottled appearance. Small calcareous and iron-oxide spheres occur locally on weathered surfaces.
Circular iron-reduction spots very rare, except in some shale intervals. Sandstone- and siltstone-conglomerates
appears to be diagenetic and may represent incipient paleosol development on a
sand. Siltstone and shale sandy, color-banded (e.g., moderate reddish brown (10R4/6) and yellowish
gray (5Y7/2)) streaks, stratified to unstratified, and with uncommon iron-reduction spots as large as 2
in. in diameter. Typically soft, weathers to “badlands”-type topography. Siltstone and shale common
near base, less so in middle of formation. In places, siltstone and shale contain evidence of paleosol
development such as blocky weathering, fractures with surfaces marked by small slickensides, or
through-going curved fractures. Thickness: about 400 ft, top not exposed
WELLINGTON FORMATION (Permian) Mostly a poorly exposed shale with minor interbedded
sandstone and siltstone. Shale is moderately to very silty and sandy; moderate reddish brown
(10R4/6), moderate red (5R5/4), with local light greenish gray (5GY8/1) streaks; concentrations and
septarian nodules rare in Wellington outcrops south of the North Canadian River. Sandstone mostly
fine to very fine grained, moderate orange pink (10R7/4) to moderate reddish brown (10R4/6),
moderate reddish orange (10R6/6) to pale red (5R6/2), mostly porous and friable, locally with
variable amounts of hematite and calcite cement. Siltstone typically color-banded consisting of pale
reddish brown (10R5/4) and light greenish gray (5GY8/1) streaks. Sedimentary structures include
large- and small-scale crossbeds, trough crossbeds, locally steeply inclined stratification, and less
common channelform features. In places, weathers to “slickrock” appearence.
The Garber-Wellington contact becomes increasingly subjective south of North Canadian River due
to the increase in thickness of shale intervals at the base of the Garber, coupled with the increase in
number and thickness of sandstone intervals toward the top of the Wellington. Also, concretionary
shales, common in upper Wellington outcrops north of the North Canadian River, are uncommon in
exposures south of the river. As a consequence, the top of Wellington is based on the first occurrence
of a thick (greater than 10 ft) Garber-like sandstone interval above in conjunction with the last
occurrence of a thick shale interval below. Thickness: varies from 620 to 720 ft, based on cross
section, but only uppermost 40 ft exposed in quadrangle
