The Upper Devonian and Mississippian stratigraphic unit polygons are vertically exaggerated to display the stratigraphic and nomenclatural complexities. In areas of considerable paleotopographic relief (e.g., carbonate reefs), the representation of stratigraphic relationships may be a compromise between time and geometry. The 'Formation' is the fundamental unit in rock stratigraphic classifications. A formation is a body of rock characterized by lithologic homogeneity; it is mappable at the Earth's surface or traceable in the subsurface. Ranks of Lithostratigraphic Units.This study delineates reservoir and non-reservoir zones in the Lower Cretaceous Dariyan Formation as units that are characteristic of the stratigraphic section representative of portions of the Persian Gulf offshore area.

Using the stratigraphic principles of Nicholas Steno: (1668) and the uniformitarian principle of James Hutton (1795), Geologists of the early 19th century could establish the relative ages of rock units on the formation scale.Sequence stratigraphy is commonly used to understand basin history and the distribution of conventional reservoir facies. Establishing a sequence stratigraphic framework in organic-rich mudstone successions is challenging because macroscale sedimentological and petrophysical variations can be subtle, while biostratigraphic and seismic data may be unavailable or of limited use.The Original reference is the citation for the original publication defining the unit. The Type locality information is usually the type area of the formation rather than a specific type locality.
