Regional Structural Cross Sections, Mid-Permian to Quaternary Strata, Texas Panhandle and Eastern New Mexico

This set consists of 12 regional cross sections (with text) of the Palo Duro, Dalhart, and Anadarko Basins, illustrating the tabular geometry of Permian evaporite beds, areas where salt has been lost by dissolution, and the effects of dissolution-induced subsidence on Permian and post-Permian strata.
The authors identify areas of dissolution beneath the High Plains, the Caprock Escarpment, the Rolling Plains, the Pecos Plains, and along the Canadian River valley. The cross sections are printed at a vertical scale of 1 inch = 400 feet and a horizontal scale of 1 inch = approximately 8 miles. They were constructed geophysical logs, sample logs, and surficial geologic data. The study was funded by the U.S. Department of Energy Salt Repository Project Office.
