Exploratory Geology of a Part of Southwestern Trans-Pecos Texas

BL2745. Exploratory Geology of a Part of Southwestern Trans-Pecos Texas, by C. L. Baker. 70 p., 1 map, 1927.


From the Introduction
The region  treated in the present paper is bounded on the north by the line of the Texas & Pacific Railway, on the west by the Malone Mountains, on the southwest by the Rio Grande, and on the east practically by the line 104" 30' west longitude. The fieldwork was done at the rate of about thirty-five square miles per day. Much of the mapping was schematic and thicknesses of rock sections were estimated. The structure proved to be complicated and only the main structural features were determined.


Keywords:  Malone Mountains, Texas, Trans-Pecos Texas
