Research

My current research integrates extensive field mapping data and petrographic work with thermodynamic modeling to evaluate metasomatic chemical reaction paths taken by acidic, high-sulfidation state hydrothermal fluids in carbonate rocks. These aqueous solutions are related to the late stages of crystallization of porphyrytic granitoid intrusions and are analogous to those recorded in active geothermal systems in volcanic arcs of the circumpacific (e.g. Pinatubo Philippines and White Island New Zealand).
The exposures created by the mine at Superior Arizona provide remarkable access to the paleogeothermal system there, allowing detailed study of 1) the geology of carbonate-hosted massive ores, 2) the chemical mechanisms of metasomatism of carbonate rocks by metaliferous solutions, and 3) the evaluation of stable isotopic tracers in determining fluid flow paths in carbonate rocks.
