From abstract: The objective of the work was to define areas showing surface indications of a generally higher uranium content where detailed exploration for uranium would most likely be successful.

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 Amarillo, Texas, Quadrangle of the National Topographic Map Series (NTMS), scale 1:125,000, was evaluated to identify and delineate geologic environments favorable for the occurrence of uranium. The study was conducted by the Bureau of Economic Geology (BEG) of the University of Texas at Austin, under subcontract to Bendix Field Engineering Corporation (BFEC), for the National Uranium Resource Evaluation (NURE) program, managed by the Grand Junction Office of the U.S. Department of Energy (DOE). The evaluation began March 31, 1978, and ended March 31, 1980. Time spent by the authors and other BEG personnel in literature search, field work, evaluation of data, and preparation of the final report totaled approximately six man-years.

Final report documenting the statistical analysis of an aerial gamma-ray and magnetic survey of the Red River Area including the Ardmore, Sherman, Abilene, and Dallas quadrangles in north Texas and southern Oklahoma. Quadrangle-specific maps and data are published as separate volumes.

From Introduction: "The Williams Quadrangle, Arizona (Fig. 1), was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for uranium deposits. Evaluations were based primarily on surface investigations; only limited subsurface data were available."

From Introduction: "The Prescott 1º by 2º quadrangle (Fig. 1) was investigated to identify areas where geologic environments exhibit characteristics favorable for uranium deposits. The defined goal was to evaluate all geologic environments to a depth of 1500 m (5,000 ft) and assign each environment to one of two categories: Favorable for uranium deposits that could contain at least 100 tons U3O8 in rocks having an average grade not less than 100 ppm U3O8. Unfavorable for such deposits."

From Introduction: "The Spokane Quadrangle, located in parts of Washington, Idaho, and Montana between lat 47º and 48º N. and long 116º and 118º W. (Fig. 1), was evaluated to identify and delineate areas and geologic units that exhibit characteristics favorable for the occurrence of uranium deposits."

From Introduction: "The quadrangle areas were evaluated to a depth of 1500m to identify geologic environments and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits"

From Introduction: "The Clifton Quadrangle, Arizona and New Mexico (Fig. 1), was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for uranium deposits. An area of approximately 20,600 km2 was evaluated during this study."

From Introduction: "The Douglas Quadrangle, Arizona and New Mexico (Fig. 1) was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for uranium deposits."

From Introduction: "The Dixon Entrance Quandrangle, Alaska (Fig. 1), was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for uranium deposits of at least 100 tons U3O8 in rocks that have a minimum grade of 100 pm U308."

From Purpose and Scope of Study: "The Lime Hills Quadrangle in south-central Alaska (Fig. 1) was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for uranium deposits."

From Introduction: "The Talkeetna Quadrangle in central Alaska (Fig. 1) was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits."

From Purpose and Scope of Study: "The Tyonek Quadrangle in south-central Alaska (Fig. 1) was evaluated to identify geologic units that have characteristics favorable for the occurrence of uranium deposits. The results of the quadrangle evaluation will be used by BFEC to estimate the amount of potential uranium resources in the study area. The uranium potential and confidence level are determined by comparison of uraniferous deposits or occurrence in the Tyonek Quadrangle with models of known uranium deposits elsewhere."

From Introduction: "The Mt. McKinley Quadrangle in central Alaska (Fig. 1) was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits."

From Introduction: "The Coleen Quadrangle, Alaska, was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits. An environment is considered favorable if it could contain uranium deposits of at least 100 tons U3O8 in rocks that have an average grade of not less that 100 ppm U3O8."

From Introduction: "The Black River Quadrangle, Alaska (Fig. 1), was evaluated to identify geologic environments that exhibit characteristics favorable for uranium deposits."

From Introduction: "The objective of this study was to present the data in a form readily useful in planning the remainder of the U.S. Department of Energy (DOE) National Uranium Resource Evaluation (NURE) Program National Aerial Radiometric Reconnaissance Survey and to facilitate planning of similar, more detailed, followup surveys in the conterminous United States. The data are presented on microfiche (in pocket) and in digital form on magnetic tape (obtainable from the DOE computer data base). The National Topographic Map Series (NTMS) quadrangles at 1:250,000 scale were used for survey unit areas in compiling the data. The data formats are explained in subsection I.B, and the nature and origin of the planning factors are described in Section II."

From Introduction: "The Las Vegas Quadrangle, Nevada, Arizona, and California (Fig. 1), was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for uranium deposits."

From Introduction: "The Nogales Quadrangle, Arizona (Fig. 1), was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits."
