The Bureau of Economic Geology—this bureaucratic title belies the essence of this organization: an ongoing group of professionals with a definite personality.

The Texas Panhandle traditionally has been an important source of mineral resources, especially petroleum, and resources will continue to contribute heavily to the economy of the area. The seven cross sections of this report synthesize the subsurface geology of the region.

The Hueco Tanks geothermal area contains five known but now inactive hot wells (50° to 71°C). The area trends north-south along the east side of Tularosa-Hueco Bolson astride the Texas-New Mexico border approximately 40 km northeast of El Paso.

Variable intensity of diagenesis is the factor primarily responsible for contrasting regional reservoir quality of Tertiary sandstones from the upper and lower Texas coast.

The publication comprises 24 structural dip cross sections, spaced 15 to 20 mi apart along the Texas coast, and 4 structural strike cross sections. Dip sections extend from near the Wilcox outcrop to the coastline.
