Rare Earth Elements: The role of geology, exploration, and analytical geochemistry in ensuring diverse sources of supply and a globally sustainable resource

The collection of papers presented in this Special Issue is grouped under the broad theme, “Rare Earth Elements: The role of geology, exploration, and analytical geochemistry in ensuring diverse sources of supply and a globally sustainable resource”. The Special Issue is intended to be an international venue for geologists, geochemists, and mineral economists to present new research with a focus on promising exploration approaches and unconventional resources of the rare earth elements (REE). The volume includes applications of geochemical analysis to develop novel approaches to deposit exploration and mine-site characterization, to understand the occurrence and genesis of REE in unconventional deposit types, and to evaluate the distribution of these elements in the surface environments in media including sediment, soils, biota, and water.
