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 purpose of the National Uranium Resource Evaluation (NURE) program of the U.S. Department of Energy (DOE) is to identify and delineate areas and environments within the Aztec 10X20 Quadrangle, New Mexico and Colorado, that exhibit characteristics favorable for the occurrence of uranium deposits that have the potential to contain at least 100 metric tons U3 08 total endowment with a minimum grade of 100 ppm (0.01 percent) U3 08 . Evaluation is based on geochemical, mineralogic, hydrologic, aerial radiometric, sedimentologic, and general geologic characteristics of the formations in the quadrangle.

Abstract: Eleven areas have been identified in the Greeley 1° x 2° Quadrangle, Colorado, that appear to be favorable for the occurrence of uranium having a minimum of 100 tons of U₃O at grades of 0.01 percent or better. Nine of these are in the Front Range metamorphic and igneous environment, and two are in the Great Plains sedimentary environment. The two favorable areas in the Plains are underlain by the Fox Hills and Laramie Formations and are favorable for "Texas" roll-type (Subclass 242) and "Wyoming" roll-type (Subclass 241) deposits. These two favorable areas have a combined area of approximately 7000 km², and they appear to have the greatest potential for uranium ore production of all the identified favorable areas. In the Front Range, the Jamestown district has a record of past uranium production and has the highest probability among the favorable areas in crystalline rocks of containing a minimum endowment of 100 tons U₃O at 0.01 percent or better. Known deposits and expected resources in the Jamestown district belong to the magmatic-hydrothermal class (Class 330), or to the autometasomatic class (Class 350), with perhaps some enrichment resulting from supergene processes (Class 360, authigenic, and Class 370, allogenic).

From Introduction: "The La Junta Quadrangle, Colorado and Kansas (Fig. 1), was evaluated to identify and delineate areas and geologic units to a depth of 1500 m (5,000 ft) that exhibit characteristics favorable for the occurrence of uranium deposits, which could contain at least 100 tons U3O8 and have an average grade of not less than 100 ppm U3O8."

From Introduction: "The Moab 1ºX2º Quadrangle, east-central Utah and west-central Colorado (Fig. 1) was studied to identify and evaluate areas and geologic formations that are favorable for the occurrence of uranium deposits of specific minimum size and grade."

From Introduction: "The Front Range region from the Wyoming-Colorado state line to southern Colorado is a uranium metallogenic province. Correspondingly, uranium has been discovered in mineable deposits in metamorphic, igneous, and sedimentary rocks formed throughout the geologic history of the region both within the Front Range itself and in the apron of sedimentary rocks that surrounds the Front Range. The Pueblo 1ºx2º National Topographic Map Series (NTMS) quadrangle, Colorado (Fig. 1), which lies within this uranium metallogenic providence, was evaluated to identify and delineate areas and geologic units that exhibit characteristics favorable for the occurrence of uranium deposits."
