DESCRIPTION OF UNITS
COVER SAND (Holocene and Pleistocene?) Unconsolidated, very fine-grained sand to
coarse-grained silt and clay, moderately to poorly sorted. Consists mainly of rounded to
subrounded quartz grains, with abundant silt- and clay-size material. Forms extensive nearly
flat topographic surfaces as much as 80 ft above modern alluvial valleys. Probably represents
aeolian reworking of Pleistocene and younger fluvial terrace deposits. Thickness: from a thin
veneer to as much as 30 ft, averages closer to 5 ft thick.
Mostly a silty claystone or clayshale depending on
whether bedding is laminated (<=1cm thick: clayshale), or thin (>1cm thick: claystone), with
local intervals of fine- to very fine-grained sandstone and coarse siltstone. The Reeding
Sandstone is the only mappable bed that can be traced with any certainty in the Hennessey
Formation.
ARTIFICIAL FILL Natural or artificial slumps, cavings, or talus covering formerly exposed
areas.
Thickness variable
ALLUVIUM (Holocene) Clay, silt, sand, and gravel in channels and on flood plains of modern
streams. Thickness: 0 to about 25 ft
ALLUVIUM OF NORTH CANADIAN RIVER (Holocene) Clay, silt, sand, and gravel in channels
and on flood plain of North Canadian River. Area probably subject to frequent flooding.
Thickness: generally 0 to 40 ft; rarely more than 40 ft
ALLUVIUM OF NORTH CANADIAN RIVER (Holocene) Clay, silt, sand, and gravel on Recent
flood plain of North Canadian River about 5 to 10 ft above Qacy. Area rarely subject to flooding.
Thickness: unknown, possibly as much as 50 ft
DUNE SAND (Holocene and Pleistocene?) Fine- to coarse-grained, moderately to poorly
sorted sand. Consists mainly of rounded to subrounded quartz grains, with some silt and clay-size
material. Probably represents eolian reworking of Pleistocene terrace deposit Qgco.
Dunes best seen east of Lake Overholser in secs. 17, 20, and 21, T. 2 N., R. 4 W. Thickness: 0 to
50 ft
REMNANTS OF OLDER TERRACE DEPOSITS (Pleistocene) Clay, silt, sand, and gravel
adjacent to the flood plain of the North Canadian River. Sand commonly is medium- to coarse-grained
and very light colored; gravel locally consists of concentrations of distally derived
pebbles and cobbles, mostly subrounded quartz and quartzite. Base of unit varies from 0 to 45 ft
above the modern flood plain of the North Canadian River and ranges in elevation to about 1260
to 1315 ft above sea level. The top of the unit is as much as 70 ft above the modern flood plain
and is as high as 1340 ft above sea level. Present only on north and east side of the North
Canadian River. Thickness: 0 to 60 ft
DUNCAN FORMATION (Permian) Sandstone, fine- to very fine grained, and minor siltstone
and shale. Lower 10 to 16 ft poorly indurated and poorly exposed; reddish orange (10R6/6) to
light brown (5YR6/4), thin- to medium-bedded, fine-grained arkosic to subarkosic sandstone
that locally fines upward to moderate reddish brown (10YR5/4) to moderate reddish orange
(10R6/6) very fine grained sandstone and siltstone. Trough cross-laminations common and
well-developed. Locally, this lower part consists of moderate reddish orange (10R6/6) to pale
brown (5YR5/2), fine- to medium-grained, poorly sorted, thin- to medium-bedded quartzwackes
interbedded with moderate reddish brown (10YR5/4) to pale olive (10Y6/2) well-laminated to
fissile clayshale and moderately indurated, thin-bedded (beds 2 to 5 in. thick) to laminated
siltstone to very fine-grained quartzwacke. Shale intervals as thick as 3 ft appear to grade
laterally into siltstone and very fine-grained sandstone intervals. The Duncan Formation
weathers to light brown or brownish-orange color compared to the underlying Hennessey
Formation. Thickness: 60 ft, top not exposed
HENNESSEY FORMATION (Permian)
Shale, silty, moderate reddish brown (10R4/6) to dark reddish brown (10R3/4); minor
siltstone, sandy, moderate reddish brown (10R4/6) to dark reddish brown (10R3/4), also
banded with yellowish gray (5Y7/2) beds; and minor sandstone, very fine grained to rarely fine-to
medium-fine-grained (near base), typically moderate reddish brown (10R4/6) to light brown
(5YR5/6) to moderate reddish orange (10R6/6), rarely yellowish gray (5Y8/1). Silty shale mostly
poorly stratified, weathers to small, angular fragments and more rarely to flakes. Contains
common iron-reduction spots, light greenish gray (5GY6/1 to 5GY8/1), as large as 2 in. in
diameter. Channelform deposits rare. Commonly weathers to bare, rounded outcrops and/or
“badlands”-type topography. Sandy siltstone generally stratified, less commonly unstratified,
and contains rare trace fossils, cross bedding, ripple marks, and shale rip-up clasts. Beds
commonly about 1 to 4 in. thick. Circular iron-reduction spots as large as 4 in. in diameter
common, locally concentrated parallel to bedding planes. Siltstone commonly weathers to
small chips, rarely spheroidal or angular blocks, in places has a “hackly” appearance. Calcite
veinlets and vugs common. Interbedded siltstone and shale weather to “badlands”-type or
bench-and-slope topography. Sandstone beds typically cross-bedded and contain ripple
marks. Lenticular- and wavy-bedding, burrows, trace fossils, mudcracks, shale rip-up clasts,
and soft-sediment deformation features uncommon. Some beds show evidence for scour and
channelform bases. Circular yellowish gray (5Y8/1) iron-reduction spots as large as 4 in. in
diameter and thin, greenish gray beds common. Sandstone friable, weathers platy to flaggy.
Thickness: about 500 ft based on cross section, base of formation not exposed
(Phyr): Sandstone, very fine grained, light brown (5YR5/6) to
moderate reddish brown (10R4/6) to moderate reddish orange (10R6/6); and minor siltstone,
moderate brown (10R4/6) and moderate reddish orange (10R6/6) and shale, dark reddish
brown (10R3/4). Contains conspicuous light greenish gray (5GY8/1) to greenish gray (5GY6/1)
circular iron-reduction spots that vary in size from very small to 5 in. in diameter and are locally
concentrated in bands parallel to bedding planes. Generally well-stratified at base to
unstratified at top; locally with low-angle cross-bedding. In places contains gray layers and
streaks that my be diagenetic. Rare vertical burrows (?). Basal contact sharp and apparently
conformable with underlying Hennessey Formation. Weathers to angular blocks. Thickness:
about 2 to 35 ft
Most deposits of this type found around man-made earthen dams and large-scale land-fills.
