A report discussing a detailed geochemical survey for uranium in and around the Grants mineral belt in New Mexico

This report discusses uranium findings from a reconnaissance of the Gallup NTMS quadrangle through water, sediment, and water samples collected from streams, springs, and wells.

Partial abstract: "During the summers of 1976, 1977, and 1978, 442 water and 1755 sediment samples were collected from 1801 locations within the 19 400 km2 area of the Moab quadrangle, Utah and Colorado, by private contractors for the Los Alamos Scientific Laboratory. Water samples were collected from streams, springs, and wells; wet and dry sediment samples were collected both from stream channels and from springs. Each water sample was analyzed for 13 elements, including uranium, and each sediment sample was analyzed for 43 elements, including uranium, thorium, and vanadium. All field and analytical data are listed in the appendixes of this report" (p. 1).

Report of uranium findings from a reconnaissance of the Gallup NTMS quadrangle through water, sediment, and water samples collected from streams, springs, and wells.

From 1995 sites in the San Juan Mountains area, 1706 water and 1982 sediment samples were collected during June-July 1976 and analyzed for uranium. The area includes the southern third of the Colorado mineral belt which has yielded rich ores of gold, silver, copper, lead, zinc, and molybdenum. The broadly domed mountains are capped by 2500 m of Tertiary volcanics, deeply eroded to expose a Precambrian crystalline core. Adjacent plateaus underlain by Mesozoic sedimentary rocks were included in the reconnaissance. Average value of uranium in water samples from mountains was less than 0.5 parts per billion, from plateaus was 1-2 parts per billion, from Mancos shale areas exceeded 2 parts per billion. Anomalous sediment samples, 40 ppm uranium, came from near Storm King Mountain and upper Vallecito Creek. Other anomalous areas, including the Lake City mining district, were well defined by 4-30 parts per million uranium in sediment and 3-30 parts per billion uranium in water. Anomalous areas not previously reported indicate favorable areas for future exploration.

Report of reconnaissance of the Albuquerque NTMS quadrangle through water and sediment samples collected from springs, wells, and streams. Samples analyzed for uranium and 42 other elements. This report is limited to samples containing uranium concentrations greater than the arbitrary anomaly thresholds of 5 parts per billion for waters and 6 parts per million for sediments.

"This report contains data for samples collected during a geochemical survey for uranium in the Cody National Topographic Map Series (NTMS) quadrangle, Wyoming, by the Los Alamos Scientific Laboratory (LASL) as part of the nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR). [...] Totals of 627 water and 1482 sediment samples were collected from 1529 locations at a nominal density of one location per 10 km2. Water samples were collected from streams, springs, and wells, and sediment samples were collected from streams and springs. Most samples were collected by two private contractors in the summers of 1976 and 1977" (p. 1).

From abstract: Between mid-May and late June 1976, 3409 water and water-transported sediment samples were collected from 1781 locations spread over an approximate 17 000 kilometer area of northwestern Montana. All of the samples were analyzed for total uranium at the LASL, using standardized procedures and rigorous quality controls--the waters by fluorometry and the sediment (and those waters with >10 parts per billion uranium) by delayed-neutron counting methods.
