Description

A subset of the National Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) data were used to produce a set of map images depicting the general geochemistry of the conterminous US. Approxiamately 260,000 samples from the continental US were analyzed. These consisted of solid samples, including stream, lake, pond, spring, and playa sediments, and soils. Data for eleven elements were analyzed and included on this release of the National Geochemical Atlas: Na, Ti, Fe, Cu, Zn, As, Ce, Hf, Pb, Th, and U.
