Research Interests:
Although primarily a metamorphic petrologist, Professor Essene's interests span the fields of mineralogy, geochemistry, and general petrology. The basic theme of his research is the application of chemical thermodynamics to the reconstruction of P-T-X histories of the earth's crust and mantle. Actual applications have included metamorphic studies in the Adirondacks and the Canadian Grenville, the metamorphism of massive sulfide deposits and iron formations, petrology of carbonates and mantle xenoliths, and studies of contact metamorphic rocks, skarns, fulgurites, and paralavas.
