Julia A. McIntosh, Ph.D.

Julia McIntosh is a Research Geologist in the Stable Isotope Laboratory at the Geology, Geophysics, and Geochemistry Science Center in Denver, CO.

Julia McIntosh utilizes light stable isotopes to characterize the formation and/or alteration of minerals from weathering, diagenetic, hydrothermal, and magmatic environments. Julia’s current research interests include fluid-mineral interactions, sediment hosted ore deposits, burial diagenesis, hydrothermal alteration, and clay mineralogy.

Stable isotope constraints on the source of ore fluids for the Hicks Dome REE+Y-HFSE-fluorspar deposit

Hicks Dome is comprised of coarse crystalline Mississippi Valley Type deposits at shallow levels and an enigmatic, fine-grained fluorite, rare earth elements, Y, high field strength elements, Be, and Ba rich deposit at deeper levels. Phyllosilicates from a lamprophyre dike and a breccia from two Hicks Dome drill cores were sampled to resolve the fluid history of the entire deposit using light stab
