Sedimentology and Depositional Environments of the Lower Permian Yeso Formation,Northwestern New Mexico (Chapter M)

摘要

In the Nacimiento Mountains of northwestern New Mexico, the Lower Permian(Leonardian) Yeso Formation is divided into a lower member, the Meseta Blanca, and an upper member, the San Ysidro. The report describes lithofacies of the Yeso Formation in northwestern New Mexico, interprets depositional environments associated with these lithofacies, and reconstructs the paleogeography of northwestern New Mexico for each member of the Yeso. Sections were measured at seven locations and then correlated to a section of De Chelly Sandstone in the Defiance Plateau of northeastern Arizona.
