Summary

This U.S. Geological Survey (USGS) data release contains analytical data from a suite of rock and mineral samples collected from drill core within the Elk Creek alkaline complex, southeast Nebraska. This complex hosts the Elk Creek carbonatite, a multilithologic carbonatite enriched in niobium, rare earth elements (REEs), scandium, and titanium. Mineralized carbonatites are the world’s primary source of rare earth elements (REEs) and niobium, but only a few deposits are responsible for meeting the current demand of these critical elements such that there is increasing interest in other carbonatites that have the potential to help meet future demands. This study focuses on the Elk Creek carbonatite, the largest Nb resource in [...]

Purpose

This data release presents a compilation of results of geochemical analyses of rock and mineral samples from drill core collected by the U.S. Geological Survey of the Elk Creek alkaline complex, southeast Nebraska. The purpose of this work was to gather information on this deposit and allow comparison with other carbonatite-hosted deposits. These data are made available for use in geologic, exploration, and environmental background studies.
