If you are interested in research projects that utilize field mapping, phase equilibrium analysis and P-T paths, geochronology, and mineral chemistry of metamorphic rocks, please contact me for further details. Possible projects include:
- Applied phase equilibria modeling of metapelites, metabasites, and metamorphosed hydrothermal alteration.
- Investigation of partial melting textures, processes and phase equilibria, timing of melting, and metamorphic zonations associated with ore deposits.
- Metamorphic phase equilibria of gahnite-bearing rocks in metamorphosed VMS deposit environments.
Background requirements: petrology, geochemisty, introduction to thermodynamics
