Rare earth element concentrations for oil shales and isolated kerogens from around the world

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2024-03-15T00:00:00Z
This Data Release contains lanthanide (i.e., rare earth element, REE), yttrium (Y), and scandium (Sc) concentrations for oil shales and kerogens isolated from those presented in the associated journal article "Role of Organic Matter and Thermal Maturation in Rare Earth Element Partitioning in the Middle Devonian Sequence of the Appalachian Basin". This dataset provides REE content for a diverse range of organic-rich mudstones from around the world with samples from the Cambrian through Eocene Periods.
