William Peck teaches mineralogy and petrology, and manages Colgate's Stable Isotope Laboratory. His research program focuses on the magmatism, metamorphism, and ore deposits of the Grenville Province, a billion-year-old exposure of mid-crustal rocks that stretches from Labrador to the Adirondack Mountains of New York.
