This dataset includes the audio-magnetotelluric (AMT) sounding data collected in 2009 in and near the San Luis Basin, New Mexico. The U.S. Geological Survey conducted a series of multidisciplinary studies, including AMT surveys, in the San Luis Basin to improve understanding of the hydrogeology of the Santa Fe Group and the nature of the sedimentary deposits comprising the principal groundwater aquifers of the Rio Grande rift. The shallow unconfined and the deeper confined Santa Fe Group aquifers in the San Luis Basin are the main sources of municipal water for the region. The population of the San Luis Basin region is growing rapidly and water shortfalls could have serious consequences. Future growth and land management...

This data release compiles the electron microprobe spot analyses of U, Th, and Pb concentrations in uraninite (U oxide) particles, and corresponding calculated age determinations, measured in samples of ore from two uranium-copper breccia pipe ore bodies, the Canyon (Pinyon Plain) and Hack II deposits. The U-rich samples that were analyzed typify the deposits hosted by solution-collapse breccia pipes in the Grand Canyon region of northwestern Arizona. Applying procedures outlined by Bowles (1990), the U, Pb, and Th measurements from each spot analysis were used to calculate a model age for the formation of each uraninite particle. The U, Pb, and Th analyses and calculated age determinations are provided as additional...

This is a geochemical data set from the reanalysis of 44 rock samples collected between 1966 and 1970, and 107 sediment samples collected in 1966 and 1967. These samples were collected by the U.S. Geological Survey for a study investigating the mineral resources of the Idaho Primitive Area (Cater et al., 1973). The samples are from the Lower Middle Fork of the Salmon River, including the tributaries of Big Creek, Camas Creek, Brush Creek, Wilson Creek, Waterfall Creek, Ship Island Creek, Reese Creek, Stoddard Creek, and Papoose Creek. The overall objective of this study is to characterize the regional impact of legacy mining for the Frank Church River of No Return Wilderness Area. Mary P. Rossillon (1981) explored...

New land-bathymetry and land-lake surface elevation models were produced for the Lake Superior region. The models combine Shuttle Radar Topography Mission (SRTM) topography data with lake surface elevation and bathymetry data sets for Lakes Superior, Michigan, and Huron. The SRTM data set was chosen because it spans the international border and has relatively high resolution at 30 m cell size. These data were subsequently used for aeromagnetic data processing and gravity data reduction.
