In 1968, the Missouri Geological Survey (MGS) established the Operation Basement program to address three objectives: a) to obtain drill hole and underground mining data relative to the structure and composition of the buried Precambrian basement; b) to expand mapping in the Precambrian outcrop area and conduct research related to Precambrian geology and mineral resources; and c) to publish the results of the first two objectives in the Contribution to Precambrian Geology series (Kisvarsanyi, 1976). The database presented here represents the first of those objectives. It was originally compiled in close cooperation with exploration and mining companies operating in Missouri, who provided drillhole data, core and...

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...
