The Morrill Limestone is a stratigraphic unit in east-central Kansas, northeast-central Oklahoma, and southeastern Nebraska in the Midwestern United States. [1] It preserves fossils dating to the Permian period.
The Oread Limestone is a geologic unit of formation rank within the Shawnee Group throughout much of its extent. It is exposed in Kansas, Nebraska, Missouri, Oklahoma, and Iowa. The type locality is Mount Oread within Lawrence, Kansas. It preserves fossils of the Carboniferous period. Although it has significant shale members, its limestone members are resistant and form escarpments and ridges. Limestone from the unit is a historic building material in Kansas, particularly in the early buildings of the University of Kansas; standing examples include Spooner Hall and Dyche Hall.
The Stanton Formation is a geologic formation of limestone in Iowa, Nebraska, Missouri and Kansas. It preserves fossils dating back to the Carboniferous period. It is in the Upper Pennsylvanian series, forming the top of the Lansing Group.
The Barneston Formation is a geologic formation in Kansas, extending into Oklahoma and Nebraska. It preserves fossils dating back to the Permian period.
The Beattie Formation, or Beattie Limestone, is a geologic formation in east-central Kansas, northeast-central Oklahoma, and southeastern Nebraska in the Midwestern United States. It preserves fossils dating to the Permian period.
The Council Grove Group is a geologic group in Kansas, Oklahoma, and Nebraska as well as subsurface Colorado. It preserves fossils dating to the Carboniferous-Permian boundary. This group forms the foundations and lower ranges of the Flint Hills of Kansas, underlying the Chase Group that forms the highest ridges of the Flint Hills.
The Barneston Limestone is a geologic formation in Kansas. It preserves fossils dating back to the Permian period.
The Wellington Formation is a geologic formation in Kansas and Oklahoma. It preserves fossils dating back to the Permian period.
The Wreford Limestone is a geologic formation in Kansas. It preserves fossils dating back to the Permian period.
The Foraker Formation is a geologic formation in Nebraska, Kansas, and Oklahoma. It preserves fossils dating to the Carboniferous period.
The Johnson Formation is a thick geologic formation of soft shale with thin, resistant beds of chalkier mudstone and limestone in Nebraska, Kansas, and Oklahoma rarely exposed outside of road cuts. It preserves fossils dating back to the late-Carboniferous period.
The Red Eagle Formation is a geologic formation in Oklahoma and Kansas. It preserves fossils dating to the Carboniferous-Permian boundary.
The Grenola Formation is an early Permian geologic formation (Wolfcampian) with its exposure running north and south through Kansas and extending into Nebraska and Oklahoma, notably having the Neva Limestone member, a terrace-forming aquifer and historic Flint Hills building stone source secondary to the Cottonwood Limestone.
The Whitehorse Formation is a geologic formation in Nebraska and Oklahoma. It preserves fossils dating back to the Permian period.
The Blanco Formation, originally named the Blanco Canyon Beds, is an early Pleistocene geologic formation of clay, sand, and gravel whitened by calcium carbonate cementation and is recognized in Texas and Kansas.
Cottonwood Limestone, or simply the Cottonwood, is a stratigraphic unit and a historic stone resource in east-central Kansas, northeast-central Oklahoma, and southeastern Nebraska in the Midwestern United States. It is the lowest member of the Beattie Limestone formation and commonly outcrops within the deep valleys and on top of the scenic residual ridges of the Flint Hills.
The Florena Shale is a stratigraphic unit in east-central Kansas, northeast-central Oklahoma, and southeastern Nebraska in the Midwestern United States. It preserves fossils dating to the Permian period.
The Neva Limestone is a stratigraphic unit and historic building stone in east-central Kansas, northeast-central Oklahoma, and southeastern Nebraska in the Midwestern United States. It preserves fossils dating to the Permian period.
The Fort Riley Limestone is a stratigraphic unit and historic building stone, sold commercially as Silverdale, in east-central Kansas, northeast-central Oklahoma, and southeastern Nebraska in the Midwestern United States. It preserves fossils dating to the Permian period.
The Fort Hays Limestone is a member of the Niobrara Formation of the Colorado Group exposed in Colorado, Kansas, Nebraska, and South Dakota and is named for the bluffs near the old Fort Hays, a well-known landmark in western Kansas.
The Roca Formation is an early Permian geologic formation (Wolfcampian) with its exposure running north and south through Kansas and extending into Nebraska and Oklahoma, notably comprising varicolored black, brown, gray, green, red, and blue shales, mudstones, and limestone, some of which representing Permian paleosols.
