Geology of the Llano Region and Austin Area

This Guidebook represents an updating of Bureau of Economic Geology Guidebook No. 5, Field Excursion-Geology of Llano Region and Austin Area. It also represents a modification of Geology of the Llano Region and Austin Area, Texas, published by the Shreveport Geological Society in 1971.

"Central Texas combines range of geologic section, quality of natural exposures, diversity of mineral commodities, and climate difficult to duplicate in an equivalent area elsewhere in the United States. A few of the interesting localities geologically were chosen to acquaint the users of this guidebook with the diversity of rock types and the range of stratigraphic section available for study in the Llano region and Austin area. The listing of geologic units recognized in the route area, the resume "Geologic History of Central Texas," and the "Schematic Section, Central Llano County to Eastern Travis County" are included so that the geologic features seen at each locality can be more readily integrated into the geologic history of the region as a whole."
