Stratigraphic formation.
The Oread Limestone, a formation common in eastern Kansas, was named in 1894 by Erasmus Haworth, the first director of the Kansas Geological Survey. He named it after Mount Oread, the hill on which the University of Kansas is located and where the limestone cropped out. The Dakota Formation, a familiar rock unit in central Kansas, got its name ...

Abstract. In the central Williston basin, USA, the Bakken Formation and overlying lower Lodgepole Formation both have fine-grained, organic-rich stratigraphic units that have been interpreted sedimentologically to represent deep-water deposition in a low-energy, distal-marine environment; however, these formations display vastly different stratigraphic geometries that challenge the ...These accumulations are in structural, stratigraphic, and combination structural-stratigraphic traps developed in a variety of rocks, including sandstone, carbonate, and granite wash (Rascoe and Adler, 1983). Pure stratigraphic traps have been found in the Missourian section, but these are small and thus far insignificant to overall production.Stratigraphy, from Latin stratum + Greek graphia, is the description of all rock bodies forming the Earth’s crust and their organization into distinctive, useful, mappable …Mt.

A formation consists of a certain number of rock strata that have a comparable lithology, facies or other similar properties. Formations are not defined on the thickness of the rock strata they consist of and the thickness of different formations can therefore vary widely.The stratigraphy of the Ecca Group has been subdivided into the Prince Albert, Whitehill, Collingham, Ripon, and Fort Brown Formations in the Eastern Cape Province, South Africa.

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.
A formation is a unit of stratigraphy. It refers to a set of sedimentary layers which are somehow distinct from those above and below them in the stratigraphic sequence. This may be because they have a different lithology, different sedimentary structures, or different fossil assemblages, or something else entirely.
