Regional Geochemical Results from the Reanalysis of NURE Stream Sediment Samples - Eagle 3 Degree Quadrangle, East-Central Alaska
Listed in NASA Earthdata CMR
This report presents reconnaissance geochemical data for a cooperative study in the Fortymile Mining District, east-central Alaska, initiated in 1997.
Description
This study has been funded by the U.S. Geological Survey (USGS) Mineral Resources Program. Cooperative funds were provided from various State of Alaska sources through the Alaska Department of Natural Resources.
Results presented here represent the initial reconnaissance phase for this multidisciplinary cooperative study. In this phase, 239 sediment samples from the Eagle 3� Quadrangle of east-central Alaska, which had been collected and analyzed for the U.S. Department of Energy’s National Uranium Resource Evaluation program (NURE) of the 1970’s (Hoffman and Buttleman, 1996; Smith, 1997), are reanalyzed by newer analytical methods that are more sensitive, accurate, and precise (Arbogast, 1996; Taggart, 2002).

The main objectives for the reanalysis of these samples were to establish lower limits of determination for some elements and to confirm the NURE data as a reliable predictive reconnaissance tool for future studies in Alaska’s Eagle 3 degrees Quadrangle. This study has wide implications for using the archived NURE samples and data throughout Alaska for future studies. [Summary provided by the USGS.]
