Douglas K. Tinkham

Associate Professor of Metamorphic Petrology; Director of the Harquail School of Earth Sciences

Telephone: 705-675-1151 ext 2270; Email: DTinkham@laurentian.ca


Dr. Tinkham arrived at Laurentian in 2005. His research is in the broad field of metamorphic geology, where he specializes in the application of thermodynamic calculations to investigate metamorphic processes and the pressure-temperature-composition evolution of rocks during metamorphism. This work is applied to rocks to decipher zoning and modification of metamorphosed hydrothermal alteration zones associated with ore deposits, metal mobility during metamorphism, partial melting of high-grade metamorphic rocks, and orogenic processes.
