Stratigraphy
Geological group:Shawnee Formation:Oread Limestone Member:Leavenworth Limestone
Stratigraphy comments: Leavenworth Limestone Member of the Oread Limestone is the "middle-limestone" of the Oread Megacyclothem (Pennsylvanian, Virgilian); stratigraphic and faunal evidence suggests that the Salem School Member of northcentral Texas is time correlative with the Leavenworth Limestone

Thickness: 1.1 feet
Lithology and environment
Primary lithology: "limestone"
Includes fossils?Y
Lithology description: "aggregate-grain-facies" Leavenworth limestone is dark bluish-gray, fine-grained, dense, very hard, vertically jointed, moderately fossiliferous; in most localities is occurs as one prominent bed ranging in thickness from slightly under 1 foot to a max. of 3 feet; skeletal mud occurs at 27 (of 32) localities and is the dominent LL facies
Environment:platform/shelf-margin reef
Geology comments: Leavenworth limestone was deposited in a relatively shallow water on a broad, slowly subsiding, carbonate platform
