John Dilles

John was born California and earned degrees in geology from Caltech (BS 1975, MS 1976) and Stanford University (PhD 1984). He has worked as an exploration geologist for Hunt, Ware & Proffett, and operated small gold mines with his brother Peter. He joined the faculty of the Oregon State University in 1986, where he is currently Emeritus Professor of Geology in the College of Earth, Ocean and Atmospheric Sciences. He has taught courses in petrology-mineralogy-geochemistry, minerals deposits, and field geology, including his Yerington mineral deposits field course that has enrolled more than 550 industry geologists and university students. He has advised 32 completed graduate degrees (MS, PhD) as well as post-docs (3), visiting scientists (3), and undergraduates (12). His research focuses on the geology of Cordilleran porphyry copper deposits, magmatic processes that generate metal and sulfur-bearing hydrothermal fluids, field-based structural geology, and isotopic tracers and geochronology. He has more that 60 peer-reviewed publications, with more than 7700 citations (h40; Google Scholar). He is a Fellow, Thayer Lindsley Lecturer, and Silver Medalist of the Society of Economic Geologists, where he has served on Council, and many committees (DEI, Student Chapter, Publications, and Distinguished Lecturer).
