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).

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."

Abstract: This data report presents supplemental analytical results for 1328 stream sediment samples that were collected as part of the SRL-NURE reconnaissance in the National Topographic Map Series (NTMS) Williamsport 1 x 2 quadrangle. Results are reported for 23 elements (extractable U, Ag, As, Ba, Be, Ca, Co, Cr, Cu, K, Li, Mg, Mo, Nb, Ni, P, Pb, Se, Sn, Sr, W, Y, and Zn). Analyses are tabulated and displayed graphically on microfiche. Field data and neutron activation analysis (NAA) were open-filed in DPST-79-146-8 [GJBX-152(79)].

From Introduction: "Uranium has been discovered in fluvial quartz-pebble conglomerates in most of the Precambrian shield areas of the world, including the Canadian, African, South America, Indian, Baltic, and Australian shields. Occurrences in these and other areas are shown in Figure 1.1. Two of these occurrences, the Huronian supergroup of Canada and the Witwatersrand deposit of South Africa contain 20-30 percent of the planet's known uranium reserves (Nininger, 1974). Thus it is critical that we understand the origin of these deposits and develop exploration models that can aid in finding new deposits."

From project objectives: The Sonora Pass region was identified by the U. S. Department of Energy (DOE) as a potential uranium resource area because of past uranium production at the Juniper Mine and reported high-grade occurrences in other buried fluvial channels which are Tertiary in age. The objective of the Sonora Pass drilling project was to obtain subsurface data that would increase the accuracy of uranium reserve estimates for the project area.

From introduction: The emanation method of uranium exploration consists of measuring the abundance of one or more uranium decay products at some distance from the orebody itself. The halo of decay products expands the exploration target and improves the chances of detection. This method assumes that indicator nuclides migrate away from the ore by some physio-chemical mechanism such as diffusion or solution in groundwater. The indicators must remain at detectable concentrations and be distinguishable from background levels. This study is concerned with gas-phase transport of Rn-222, Xe-133, and He-4 away from uranium ore deposits. The first of these indicator nuclides, Rn-222, is a member of the uranium series decay chain (Table 1) and has a 3.82 day half-life. The second, Xe-133,. is a spontaneous fission product which has a half-life of 5.26 days. Finally, He-4 is a stable nuclide created from alpha particles emitted by various members of the uranium, actinium, and thorium decay series.

From objective and scope: The objective of this report us to provide a descriptive body of knowledge on Cordilleran metamorphic core complexes including their lithologic and structural characteristics, distribution within the Cordillera, and their evolutionary history and tectonic setting. We also examine the occurrence of uranium in the context of possibility for uranium concentration.
