William Peck teaches Mineralogy and Petrology and manages Colgate's Stable Isotope Laboratory.  His research program focusses 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. 

Petrology, tectonics, magmatism, and ore deposits in the Adirondacks and Grenville Province
Anorthosite petrogenesis
Petrology of zircon and metamorphic zircon growth 
Origin of cordierite-gedrite rocks
Conditions of the early Earth
Carbon isotopes in minerals with trace carbon (apatite, cordierite, beryl)
Carbon isotopes in maple, birch, and walnut syrup
Weathering of wollastonite and carbon sequestration
