Geophysical logs for 12 holes drilled for the Oakville-Goliad Project in the Laredo-McAllen Quadrangles, Texas by the Bendix Field Engineering Corporation, Grand Junction, Colorado.

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).

Appendices containing data on uranium availability in the Lawton Quadrangle to accompany a report on U.S. uranium resources in Oklahoma and Texas.

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
