National Uranium Resource Evaluation, Llano Quadrangle, Texas

Technical Report · Thu Apr 01 04:00:00 EST 1982

OSTI ID:5366478

Droddy, M J; Hovorka, S D

The Llano 2/sup 0/ quadrangle was evaluated to a depth of 1500 m to identify environments and delineate areas favorable for the occurrence of uranium deposits. The areas were delineated according to criteria established for the National Uranium Resource Evaluation program. Surface studies included investigations of uranium occurrences described in the literature, location of aerial radiometric anomalies, carborne scintillometer surveys, outcrop investigations, and followup of hydrogeochemical and stream-sediment reconnaissance data. A radon emanometry survey and investigations of electric and gamma-ray well logs, drillers' logs, and well core samples were performed to evaluate the subsurface potential of the Llano Quadrangle. An environment favorable for pegmatitic deposits is identified in the Town Mountain Granite.
