The geology of Oklahoma is characterized by Carboniferous rocks in the east, Permian rocks in the center and towards the west, and a cover of Tertiary deposits in the panhandle to the west. The panhandle of Oklahoma is also noted for its Jurassic rocks as well. Cretaceous sediments are found in the south east.
Oolite – Sedimentary rock formed from ooids; Rag-stone – Work done with stones that are quarried in thin pieces; Shelly limestone – Limestone containing many fossils; Travertine – Form of limestone deposited by mineral springs; Tufa – Porous limestone rock formed when carbonate minerals precipitate out of ambient temperature water
In North America, where the early Carboniferous beds are primarily marine limestones, the Pennsylvanian was in the past treated as a full-fledged geologic period between the Mississippian and the Permian. In parts of Europe, the Mississippian and Pennsylvanian are one more-or-less continuous sequence of lowland continental deposits and are ...

The Morrow facies (body of rock with specific characteristics) was deposited in a complex of mixed siliciclastic (mostly silica bearing rock) and carbonate depositional environments. [5] The Morrow Formation is typically divided into two intervals: The Morrow clastics; The overlying Morrow limestones; Source: [6]
The Mississippian (/ ˌ m ɪ s ɪ ˈ s ɪ p i. ə n / MISS-iss-IP-ee-ən), [5] also known as Lower Carboniferous or Early Carboniferous, is a subperiod in the geologic timescale or a subsystem of the geologic record. It is the earlier of two subperiods of the Carboniferous period lasting from roughly 358.9 to 323.2
Carboniferous rocks underlie the thick recent deposits north of Ramsey and around Andreas but are nowhere seen at the surface. At the top of the Carboniferous sequence, a suite of igneous rocks which outcrop on the eastern side of Bay ny Carrickey opposite Port St Mary which include tuffs , pillow lavas and debris flows are collected together ...
The earliest Carboniferous rocks sit conformably on top of the youngest Devonian in Illinois; Carboniferous rocks in the state are areally extensive, regionally very well-exposed, and form a large percentage of the state's bedrock. Illinois remained marine for much of the Carboniferous, with limestones making up most of the rock deposited ...
