This report presents engineering details, statistics, individual borehole histories, and geophysical logs of the 12 holes drilled for this project.

From purpose and scope: The Lawton Quadrangle, Oklahoma and Texas (Fig. 1), was evaluated to a depth of 1500 m (5,000 ft) to identify geologic environments and delineate areas that exhibit characteristics favorable for uranium deposits. Determination of uranium favorability was based on the similarity of geologic characteristics to the National Uranium Resource Evaluation (NURE) recognition criteria described in Mickle and Mathews (eds., 1978).

Appendix containing a series of reports documenting uranium occurrences in deposits found in the Plainview quadrangle, Texas.

Discussing the evaluation made of the Plainview NTMS Quadrangle to identify and delineate areas and geologic units that exhibit characteristics favorable for the occurrence of uranium deposits.

The U. S. Atomic Energy Commission conducted an airborne radioactivity survey of the Red River region of Texas and Oklahoma beginning in December 1955 and ending in May 1956. All or parts of Archer, Clay, and Montague Counties in northern Texas and Carter, Cotton, Jefferson, and Stephens Counties in southern Oklahoma were surveyed. Particular attention was paid to those areas where exposures are found of red beds of the Permian Wichita Group. Field examinations were conducted of anomalies discovered by airborne reconnaissance as well as those reported by private individuals. Forty localities were examined, the majority in sandstones, siltstones, or conglomerates. Uranium and copper minerals were identified at several localities. Ferruginous staining, bleaching of the sandstone color, calcium carbonate cement, and carbonized plant remains are common to the deposits

A report discussing groundwaters from aquifers in two different sandstone-type uranium mining districts in Texas and Wyoming that were collected and chemically analyzed.

Purpose and Scope: "The McAllen and Brownsville Quadrangles, Texas (Fig. 1), were evaluated to a depth of 1500 m (5,000 ft) to identify geologic environments and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits. Favorable environments, as determined by surface and subsurface investigation, are those that could contain uranium deposits of at least 100 tons U3O8 at an average grade not less than 100 ppm U3O8."

From Introduction: "The Laredo Quadrangle, Texas (Fig. 1), was evaluated to a depth of 1500 m (5,000 ft) to identify geologic environments and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits."

This report presents rock sample and uranium data examined from the Van Horn, Texas area. Over 300 rocks samples were analyzed for 30 elements.

From Purpose and Scope: "The Beeville Quadrangle, Texas, was evaluated to a depth of 1500 m (5,000 ft) to identify geologic environments and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits."

Results of reconnaissance surveys of the Llano quadrangle to determine the likelihood of uranium deposits of the area, and additional information about the location and classification of any deposits.

Discussing the results of a Radon cup Survey for the Llano Quadrangle

From Introduction: "The Seguin Quadrangle, Texas, was evaluated to a depth of 1500 m (5,000 ft) to identify geologic units and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits. Each geologic environment was categorized as favorable, unfavorable, or unevaluated for uranium deposits, based on recognition criteria obtained from the study of significant uranium districts worldwide (Mickle and Matherws, eds.1978)."

Results of reconnaissance surveys of the Presidio quadrangle to determine the likelihood of uranium deposits of the area, and additional information about the location and classification of any deposits.

The following report is the first volume documenting the radiometric and magnetic data taken during the month of October, 1979, by EG&G geoMetrics primarily in the state of Texas in the quadrangles: Tyler, Texarkana, and Waco.
