Report documenting results of analysis for airborne gamma radiation and total magnetic field survey for the Hobbs National Topographic Map Sheet (NI 13-12). It includes data calculations and profiled data readings with a general description of the area and corresponding data readings.

From abstract: During fiscal years 1978 through 1981, the U.S. Geological Survey contracted for the acquisition and analysis of hydrologic data from 104 surface water stations, 26 ground water stations, and 15 precipitation gages as well as for several hundred miscellaneous surface water measurements of flow and water quality. The work was performed in Montana, North Dakota, Wyoming, Utah, New Mexico, and Oklahoma, terminating at the end of the fiscal year 1981. This report is an assessment of this contracting effort from the standpoint of cost and of quality control measures employed to ensure an acceptable product.

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.

GEOTHERM sample file contains 251 records for New Mexico. Three computer-generated indexes are found in appendices A, B, and C of this report. The indexes give one line summaries of each GEOTHERM record describing the chemistry of geothermal springs and wells in the sample file for New Mexico. Each index is sorted by different variables to assist the user in locating geothermal records describing specific sites. Appendix A is sorted by the county name and the name of the source. Also given are latitude, longitude (both use decimal minutes), township, range, section, GEOTHERM record identifier, and temperature (/sup 0/C). Appendix B is sorted by county, township, range, and section. Also given are name of source, GEOTHERM record identifier, and temperature (/sup 0/C). Appendix C is first sorted into one-degree blocks by latitude, and longitude, and then by name of source. Adjacent one-degree blocks which are published as a 1:250,000 map are combined under the appropriate map name. Also given are GEOTHERM record identifier, and temperature (/sup 0/C). A bibliography is given in Appendix D.

From abstract: Drillhole DOE-2 was drilled to investigate a structural depression marked by the downward displacement of stratigraphic markers in the Salado Formation ~ 2 mi north of the center of the WIPP site. This depression was named informally after the shallow borehole FC-92 in which the structure was described. The presence of the depression was confirmed by drilling.

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.

Discussing samples collected by the Los Alamos National Laboratory for a detailed geochemical survey of uranium in the northern San Andreas Mountains and the Oscura Mountains of south-central New Mexico.

From purpose and scope: The purpose of this study was to estimate the natural streamflow in the Rio San Jose at the upstream boundaries of the Pueblos of Acoma and Laguna. Natural streamflow is defined for this study as the streamflow that would have occurred if water development in the basin upstream from the pueblos had never taken place.

A three-dimensional model was created to estimate vertical hydraulic conductivity and regional ground-water flow rates in rocks within the San Juan Basin in New Mexico and Colorado.

From introduction: This report describes the results of 1980 sampling of ground-water pumpage for irrigation on the High Plains, one phase of the High Plains Regional Aquifer-System Analysis project. These data were collected to estimate the volume of irrigation water pumped during 1980 and to determine current trends in irrigation pumpage on the High Plains.

From introduction: At the request of the U.S. Bureau of Indian Affairs, the U.S. Geological Survey conducted the present study to estimate natural streamflow in the Jemez River at the boundaries of the various Indian lands. Natural streamflow is defined as the streamflow that would occur if there had been no man-made changes in the hydraulic characteristics of the river basin.

From introduction: "The U.S. Geological Survey began a 5-year study of the High Plains regional aquifer during the 1978 to provide the hydrologic information needed for the development of computer models to evaluate the aquifer's response to ground-water management alternatives." It contains maps, graphs, and tables.

From abstract: This report describes the depositional environments of the Chinle Formation that was deposited in a complex fluvial-deltaic-lacustrine system in the area of the present-day eastern San Juan basin and Chama basin. Lithofacies include conglomerate and planar- and trough-crossbedded sandstone; bentonitic mudstone and sandstone; black, organic carbon-rich mudstone; large-scale, trough crossstratified siltstone, sandstone, and mudstone; and thickbedded, bioturbated, fine-grained sandstone and siltstone.

From purpose and scope: This report discusses the ground-water systems and the interpretation of test results in the water-bearing zones above and below the proposed facility, Waste Isolation Pilot Plant (WIPP) in Los Medanos.

From introduction: The U.S. Geological Survey is participating in this evaluation by developing information on the ground-water hydrology of the region, obtaining geologic borehole data, and conducting hydrologic tests in boreholes on and near the WIPP site. This report provides well-construction information and lithologic data about the Rustler and Salado Formations and the top of the salt interval within the Salado Formation at the H-8 borehole complex.

This following report discusses the studies and findings of the East Chaco Canyon drilling project of northwestern New Mexico. These studies took place between July and November of 1978.

Extended literature review describing the geologic history and characteristics of the Grants Uranium Region in northwestern New Mexico, particularly the uraniferous humate uranium deposits, "for the purpose of describing those geologic recognition criteria which seem most useful for evaluating areas with potential for new deposits" (p. 13).

Introduction: This report is a brief review of the uranium and/or vanadium mining in the eastern Carrizo Mountains, San Juan County, New Mexico and Apache County, Arizona. It was prepared at the request of the Navajo Tribe, the New Mexico Energy and Minerals Department, and the Arizona Bureau of Geology and Mineral Technology. As this report deals only with historical production data, the reader is referred to reports by Blagbrough and Brown (1955), Masters and others (1955), and Stokes (1951, 1954) for descriptions of the geology and ore deposits. Figure 1 shows the locations of the mines and the production is summarized in Table 1 and Figure 2. A separate report (Chenoweth and Learned, 1980) covers the production history of the northern and western Carrizo Mountains.
