The Permian Basin deposit includes the major mines outside of Carlsbad, New Mexico, to the world's purest potash deposit in Lea County, New Mexico (near the Carlsbad deposits), which is believed to be roughly 80% pure.
Early studies by Udden, and the presence of potash in the Santa Rita well between 1,100 and 1,700 feet, led to the United States Geological Survey exploring the area in search of potash, which was highly important during World War I as the US could no longer import it from Germany. By the mid-1960s, seven potash mines were operating on the New ...

By earliest Permian time, during the Wolfcampian Epoch, the ovoid shaped subsiding Delaware Basin extended over 10,000 square miles (26,000 km 2) in what is now western Texas and southeast New Mexico. [1]: 193§1 This period of deposition left a thickness of 1,600 to 2,200 feet (490 to 670 m) of limestone interbedded with dark-colored shale.

Map of Mesozoic exposures in New Mexico, USA. The Mesozoic began with the Permian-Triassic extinction event. [31] The Sevier and Nevadan orogenies pushed up mountains to the west of New Mexico that produced a rain shadow, giving New Mexico an exquisitely hot and dry climate through much of the early Mesozoic.
