Allen Andersen, PhD

Allen is a Research Geologist with Geology, Minerals, Energy, and Geophysics Science Center. He received PhD and MSc degrees in Geology from Washington State University and a BSc degree in Geology from Northwest Missouri State University. Allen works on projects related to economic geology.


Allen's broader interests include the genesis of magmatic-hydrothermal ore deposits, geochemistry applied
to the assessment of critical mineral resources, fluid-rock interaction, and ore-forming processes of
critical mineral deposits. More specifically, his work focuses on the geology of rare earth element (REE)
deposits, the behavior of REE in fluids and carbonatite magmas, and mineral resources associated with
Paleogene magmatism across western North America. Allen also maintains interest in the formation of
magmatic ore deposits enriched in platinum-group elements, chromium, nickel, copper, cobalt, titanium,
and vanadium. Prior to joining the USGS, he spent more than six summers as a consulting geologist in the
mineral exploration industry.
