Dr. Joyashish Thakurta is assistant professor of igneous petrology and economic geology in the Department of Geosciences at Western Michigan University. Thakurta focuses his research on the origin of magmatic intrusive bodies and the occurrences of magmatic and hydrothermal sulfide mineral deposits of base and precious metals associated with such intrusions. He emphasizes the economic importance of Ural-Alaskan type complexes and its origin. He works on the petrogenesis and geochemical characterization of a selected group of Ural-Alaskan type complexes in southeastern Alaska. Thakurta is interested in the metallic sulfide mineral deposits located in the Upper Peninsula of Michigan related to the Penokean orogeny (1.8 Ga) and the magmatic events associated with the formation of the Mid-continent Rift system (1.1 Ga). He is also interested in applications of stable isotope geochemistry in high temperature geological processes. He operates a Delta-V isotope ratio mass-spectrometer in his Economic Geology Laboratory for the collection of stable isotope data.
