Title: “Fluid-rock interaction and hydrothermal REE transport in critical mineral deposits”

Abstract:  Large REE mineral deposits are found in carbonatites and (per)alkaline complexes, many of which are found in North America. This presentation gives an overview of ore-forming processes in critical mineral deposits and our current understanding of alteration zoning, mineralogy, and geochemical vectoring. The combination of field observations with frontiers in science from hydrothermal experiments and thermodynamic modeling yields key insights into the controls on REE transport, fractionation and deposition in natural systems. But how can we effectively link these insights to interpret geochemical data in these mineral deposits?

Biography: Dr. Gysi currently holds a dual appointment at as an Economic Geologist in the New Mexico Bureau of Geology and Mineral Resources and as an Associate Professor in the department of Earth & Environmental Science at New Mexico Tech. He has a broad interest in hydrothermal ore deposit formation and metasomatism, with a focus on critical mineral deposits, including carbonatites, alkaline igneous rocks and pegmatites.
