The West Texas Permian Basin

The Permian Basin is a sedimentary basin largely contained in the western part of the U.S. state of Texas and the southeastern part of the U.S. state of New Mexico. It reaches from just south of Lubbock, to just south of Midland and Odessa, extending westward into the southeastern part of the adjacent state of New Mexico. It is so named because it has one of the world's thickest deposits of rocks from the Permian geologic period. The greater Permian Basin comprises several component basins: of these, Midland Basin is the largest, Delaware Basin is the second largest, and Marfa Basin is the smallest. The Permian Basin extends beneath an area approximately 250 miles (400 km) wide and 300 miles (480 km) long.[1]

Depositional history

[edit]

The Permian Basin is the thickest deposit of Permian aged rocks on Earth which were rapidly deposited during the collision of North America and Gondwana (South America and Africa) between the late Mississippian through the Permian.

Lower Paleozoic (Upper Cambrian to Mississippian)

[edit]

Prior to the breakup of the Precambrian supercontinent and the formation of the modern Permian Basin geometry, shallow marine sedimentation onto to the ancestral Tobosa Basin characterized the passive margin, shallow marine environment.

Upper Mississippian-Lower Permian

[edit]

The collision of North America and Gondwana Land (South America and Africa) during the Hercynian Orogeny created the Ouachita-Marathon thrust belt and the associated foreland basins, the Delaware and Midland Basins, separated by the Central Basin Platform. The tectonic activity resulted in the distribution of voluminous siliciclastic sediments into the basins during the Early Pennsylvanian. Siliciclastic sedimentation was followed by the formation of carbonate shelves and margins at the basin flanks in the Early Permian.

Counties of the Permian Basin

[edit]

The Permian Basin has also given its name to the geographic region in which it lies. The counties of this region include:[citation needed] [2]

It's hard to find sources on permian basin as a region with these counties. Could instead have list of counties overlying the basin as well as a list of counties involved in the Permian Basin Regional Planning Commission? [[1]]

According to the 2008/2009 census, the Permian Basin had a population of 522,568.

Other counties sometimes considered part of the Permian Basin are:[citation needed]

If one includes those counties, then the population of the Permian Basin comes to 577,667.[citation needed]
