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.
OLDER ALLUVIUM (Holocene) Mostly sand, with variable amounts of clay and silt-sized material,
and little to no gravel-sized material; situated from 10 to 20 ft above modern flood plain terraces.
Thickness at least 30 ft.
WANN FORMATION (Pennsylvanian, Missourian) Consists of four predominant sandstone
intervals, each separated by predominant shale intervals starting at the base of the formation.
Sandstones, very pale orange (10YR8/2), pale yellowish orange (10YR8/6) to moderate orange
pink (5YR8/4), grayish orange pink (5YR7/2), and yellowish gray (5Y7/2); sandstone intervals vary
between 5 to 15 ft thick, consisting of weakly indurated to indurated, fine- to medium-grained, locally
coarse-grained at base, calcareous to weakly siliceous, quartz-rich arenites; thin- to medium- planar
bedding, locally cross-laminated at base of some intervals, with individual beds varying from 1.5” to 6”
thick; clayshale partings and thin (< 5” thick) intervals occur locally near top of sandstone intervals;
molds of Linoproductid brachipods and fusulinids, horizontal burrows, tracks, and tool marks common
in some sandstone beds in lower part of formation. The most prominent sandstone intervals are the
Washington Irving Sandstone, located about 50 ft above the base, and the Clear Creek Sandstone,
which is usually located from 90 to 100 ft above the formation’s base.
Shale intervals vary from 5 ft to as much as 50 ft thick, with the thicker intervals occurring at the base
and top of the formation; consists of yellowish gray (5Y7/2), dusky yellow (5Y6/4), and medium light
gray (N6) hues in lower stratigraphic intervals, but grading upward into dark yellowish orange
(10YR6/6) to moderate reddish brown (10R4/6) hues toward top; texturally, laminated to well-laminated,
slightly silty to very silty clayshale and mudstone. Mudstone intervals more common in
upper part of formation; very fine-grained sandstone and siltstone interbeds common in the upper part
of each shale interval. Thin (6” thick or less), argillaceous carbonate mudstones occur locally at the
base of some shale intervals, particularly just above the Washington Irving and Clear Creek
sandstone intervals.
Exposed thickness of formation at least 150 ft, top not exposed.
IOLA FORMATION (Pennsylvanian, Missourian) Poorly exposed in quad. Consists of three
members, which are, in descending order: 1) Avant Limestone; 2) Muncie Creek Shale; and 3) Paola
Limestone. Total thickness of the formation varies from 25 to 63 ft, depending on the thickness of the
middle clastic unit within the Avant Limestone.
: Consists of an upper and lower limestone, separated by and an intervening
interbedded sandstone and shale interval. The Avant Limestones are typically medium gray (N5) to
medium light gray (N6), medium- to locally thick-bedded, algal wackestone and carbonate mudstone;
bedding is irregular and varies from 3” to as much as 4’ in thickness; the upper Avant Limestone is the
thicker of the two limestones and attains a thickness between 10’ to 20’; the lower Avant Limestone is
usually 3’ thick or a little less. The intervening clastic interval is about 10’ to 15’ of fine-grained
sandstone interbedded with slightly silty clayshale; shale is more common in the lower half of this
interval.
: Predominantly a medium gray (N5), well-laminated, slightly silty, calcareous,
fossiliferous clayshale; basal 2’ to 5’ a dark gray (N3) to grayish black (N2), fissile, phosphatic
clayshale; fossils mostly include chonetid brachiopods, ramose and fenestrate bryozoans, and
crinoid debris. Thickness of the Muncie Creek about 25 ft.
: Usually a single bed of medium light gray (N6), sandy, skeletal wackestone to
packstone; ooids and glauconite may occur locally. Thickness averages 1 ft or less.
CHANUTE FORMATION (Pennsylvanian, Missourian) Mostly a grayish orange (10YR7/4), grayish
orange pink (5YR7/2), pale yellowish brown (10YR6/2), to medium light gray (N6), laminated to blocky
bedded, weakly calcareous, very silty clayshale to mudshale; silt content and blocky nature of
bedding increases toward top of formation. Locally, an 8’ to 10’ thick, indurated, laminated to thin-bedded,
fine to very fine-grained sandstone, which may correlate with the Cottage Grove Sandstone,
occurs near the top of the formation. The Thayer Coal also occurs within this unit, but was not
observed in the field area.
Total thickness of the formation varies from 50 to 70 ft thick.
DEWEY FORMATION (Pennsylvanian, Missourian) Consists of two thin, slightly sandy limestone
beds with an intervening shale and sandstone interval. Limestones are moderate red (5R4/6),
moderate reddish brown (10R4/6), to dusky red (5R3/4), thin-bedded to locally laminated, sandy,
fossiliferous packstone to rarely grainstone; if present, grainstone textures found only in upper-most
limestone bed; fossils dominated by small bivalves, high-spired gastropods, and crinoid debris.
Thickness of both limestone beds average 2 ft, although upper limestone may achieve thicknesses in
excess of 3 ft.
Intervening clastic interval mostly dark yellowish brown (10YR6/6) to moderate reddish brown
(10R4/6), laminated, calcareous, fossiliferous clayshale, grading upward into very fine-grained,
laminated sandstone and siltstone; large productid brachiopods common in shale interval.
Thickness of the Dewey varies considerably in the map area, attaining a thickness of 40 ft in the
north, but only 25 ft thick in the southern half of the quad.
NELLIE BLY FORMATION (Pennsylvanian, Missourian) C
HOGSHOOTER FORMATION (Pennsylvanian, Missourian) In the northern half of quad, formation
composed of an upper, thin Winterset Member and a lower, thicker Lost City Member. The Lost City
member pinches out in the southern half of the map area. Total thickness of formation varies from as
much as 52 ft thick to as little as 2.5 ft thick, depending on the presence or absence of the Lost City
Member.
COFFEYVILLE FORMATION (Pennsylvanian, Missourian) Exposed parts of the formation include
a light olive gray (5Y6/1) to medium gray (N5), well-laminated to fissile, slightly silty clayshale and the
Dodds Creek Member (the base of which is denoted by ‘dc’). Texturally, the Dodds Creek in the Lake
Sahoma quad is similar to that observed in the Sapulpa North quad to the east.
Exposed thickness of the Coffeyville about 60 ft.
CHECKERBOARD LIMESTONE (Pennsylvanian, Missourian) A dense skeletal to whole-fossil
carbonate mudstone to wackestone; found only in the subsurface.
SEMINOLE FORMATION (Pennsylvanian, Missourian) Formation consists of a lower sandstone
interval called the Tulsa Sandstone and a basal and upper suite of interbedded laminated,
concretionary, silty clayshales, mudshales and siltstones. The Tulsa coal also occurs within the
uppermost shale interval, just above the top of the Tulsa Sandstone; found only in the subsurface.
LOST BRANCH FORMATION (Pennsylvanian, Desmoinesian) Overall, a laminated, slightly
calcareous, micaceous, silty clayshale, phosphatic clayshale, and thin limestone beds; found only in
the subsurface.
MEMORIAL FORMATION (Pennsylvanian, Desmoinesian) Interbedded sandstones and shales
with a prominant coal bed (Broken Arrow coal) at top; found only in the subsurface.
LENAPAH FORMATION (Pennsylvanian, Desmoinesian) A thin, skeletal to whole fossil
wackestone to packstone textured limestone; found only in the subsurface.
NOWATA FORMATION (Pennsylvanian, Desmoinesian) A blocky-bedded to weakly laminated,
slightly silty, concretionary clayshale; found only in the subsurface.
OOLOGAH FORMATION (Pennsylvanian, Desmoinesian) A thin- to medium-bedded, skeletal
carbonate mudstone to wackestone; found only in the subsurface.
LABETTE FORMATION (Pennsylvanian, Desmoinesian) A laminated, very silty to sandy,
micaceous, concretionary clayshale, interbedded with fine-grained sandstones near top; found only
in the subsurface.
FORT SCOTT FORMATION (Pennsylvanian, Desmoinesian) Thin to medium, wavy bedded whole-fossil
wackestones and mudstones, interbedded with fissile, phosphatic clayshale; found only in the
subsurface.
SENORA FORMATION (Pennsylvanian, Desmoinesian) Complex sequence of silty and
concretionary clayshale, interbedded with very fine-grained sandstones, siltstones and coal. Unit
includes the Tiawah Limestone bed. Formation found only in the subsurface.

onsists mostly of clayshale and
mudstone, interbedded with some prominent sandstones, none of which can be easily separated into
mappable units. Sandstones vary from yellowish gray (5Y7/2), dusky yellow (5Y6/4; when moist), pale
yellowish orange (10YR8/6), grayish orange (10YR7/4), and pale greenish yellow (10Y8/2) when
fresh; commonly dark yellowish orange (10YR6/6), although it may be moderate yellowish brown
(10YR 54) or light brown (5Y5/6) weathered; all exhibit moderate induration, rarely friable, are quartz-rich,
fine- to very fine-grained, and non-calcareous, although some bedding surfaces may be
calcareous due to the precipitation of caliche. Fe-oxide spots, trace fossils, laminations and cross-laminations,
ripple marks, and tool marks are common along bedding surfaces; mud clasts and pitting
from weathering of mud clasts are sometimes observed, and soft-sediment deformation is rare. Some
prominent sandstones do occur locally: an unnamed, 8-10 ft thick interval of thin- to medium-bedded
(bedding 1-3 ft thick), homogenous sandstone occurs between 15 to 25 ft above the Hogshooter
Formation. Another prominent sandstone, called the Shell Creek Sandstone occurs between 75 to
125 ft above the base. Good exposures of the Shell Creek Sandstone indicate a wide variety of
lithologic textures, ranging from a thick-bedded with thin clayshale to a thin-bedded sandstone
interval with appreciably more clayshale content. Other sandstones of even more local significance
vary from laminated to medium-bedded, with planar to wavy bedding contacts.
Interbedded shales are a light olive gray (5Y5/2; 5Y6/1) to olive gray (5Y4/1) and consist
predominantly of slightly silty claystones to mudstones, although clayshale textural bedding is not
uncommon; paleosol development and curved slickenside fractures common in mudstone and
claystone lithologies. Ironstone concretionary layers may be present within shales; concretions
commonly moderate yellowish brown (10YR5/4) to moderate brown (5YR4/4) in color.
Total thickness of formation 350 ft.
The Winterset Member is usually represented by a single bed (< 3’ thick) of whole fossil packstone,
with lesser amounts of wackestone and carbonate mudstone textures; thin (1”-3” thick) wavy bedding
may be observed in the upper half of the member, locally. Fossils include abundant crinoid stems and
ossicles, brachiopods, clams, bryozoans, corals, and algae. Packstone colors include light olive gray
(5Y6/1), olive gray (5Y4/1), medium light gray (N6) and medium gray (N5). Weathered surfaces
include dusky yellow (5Y6/4), moderate yellowish brown (10YR 5/4), and dark yellowish orange
(10YR6/6). Carbonate mudstone is light olive gray (5Y6/1) and weathers grayish orange (10YR7/4),
dark yellowish orange (10YR6/6), and light brown (5YR5/6), is well indurated, and contains few, if any,
fossils; locally, carbonate mudstones may be slightly sandy or contain carbonaceous matter.
Ironstone nodules are sometimes observed where internal bedding is present in the member.
The Lost City Member consists of a medium light grey (N6) to medium gray (N5) fresh, locally
weathered to a light brown (5YR5/6) or moderate yellowish brown (10YR5/4) color along fractures
and bedding planes, whole-fossil to locally skeletal wackestone or carbonate mudstone; bedding thin
to thick, varying from 1” to as much as 3’ thick; thinner bedding more common in the middle third of
member, where bedding is commonly wavy and varies between 1” to 5” thick, the upper and lower
third of member is typically medium to thick bedded, with bedding varying from 2’ to 3’ thick. Enclosed
fossil assemblages are similar to that of the Winterset Member. Overall, member thickness is
between 40 to 50 ft thick.
