National Uranium Resource Evaluation Program: Sediment Chemistry of the Conterminous United States

From NURE Sediment Chemistry FAQ: These maps are derived from a subset of the National Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) data. Approximately 260,000 samples were analyzed in the continental U.S. and consisted of solid samples, including stream, lake, pond, spring, and playa sediments, and soils. Data for eleven elements: Na, Ti, Fe, Cu, Zn, As, Ce, Hf, Pb, Th, and U were analyzed and included on the National Geochemical Atlas CD and the digital release NURE Sediment Chemistry. These publications are intended to allow the rapid visualization of the geochemical landscape of the conterminous U.S. using NURE HSSR data. The raw data used in the production of these publications are available on the following CD-ROM: Hoffman, J.D., Kim P. Buttleman, Russell A. Ambroziak, and Christine A. Cook, 1996, National Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) data. available
