Summary

This data release compiles major and trace element analytical results of samples of bauxite (aluminum ore) and associated rocks collected from the Arkansas bauxite region, located near the center of Arkansas in Pulaski and Saline Counties. Samples were collected by the U.S. Geological Survey (USGS) in April 2018 as part of the USGS' focus on increased understanding of the United States' critical mineral resources. Mineral commodities, based on USGS studies, have been designated as critical where the United States is predominantly reliant on foreign sources (McCullough and Nassar, 2017; Fortier and others, 2018). The five primary aluminum smelters in the U.S., in 2017 and previous years, were dependent on imported bauxite as their raw [...]
