Upper Permian Ochoa Series of Delaware Basin, West Texas and Southeastern New Mexico

Abstract

ABSTRACT The Ochoa series includes the uppermost Permian deposits of the southwestern United States. Most of the rocks included in the series are poorly exposed unfossiliferous evaporites. The well known subsurface section in and around the Delaware basin is described and illustrated by cross sections. A short chapter discusses theories on the origin and distribution of the characteristic evaporites.
