From abstract: The High Plains Regional Aquifer System Analysis study has developed a regional water-resources (and related) data storage and retrieval system to organize and preserve areal interpretive data. The system is general and can easily be adapted for other studies. This report documents the High Plains data base as well as the general system that is independent of the High Plains area.

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).

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."

From Introduction: "The Corpus Christi 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 uranium deposits."

From Abstract: "Uranium resources of the Austin Quadrangle, Texas, were evaluated to a depth of 1500m. Criteria developed for the National Uranium Resource Evaluation program were used to delineate areas and identify environments favorable for the deposition of uranium. Uranium occurrences reported in the literature were located, described, and sampled."

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)."

From Introduction: "The Crystal City Quadrangle, Texas, was evaluated to a depth of 1500 m (5,000 ft) to identity geologic units and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits."

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."

From Introduction: "The Beaumont Quadrangle, Texas (National Topographic Map Series), 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."

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."
