Michael Cosca is a research geologist with the U.S. Geological Survey, who combines 40Ar/39Ar geochronology with mineralogy, petrology, and field geology to understand igneous, metamorphic, and tectonic processes at the regional, local, and sub-grain scale. Mike received his undergraduate degree in geology from the University of California, Berkeley (1981) and M.Sc. (1985) and Ph.D. (1989) in geology from the University of Michigan
geochronology of ore deposits, mountain building, volcanic stratigraphy, landscape formation, near-surface faulting, physical and chemical controls of argon distribution
