Research Professor, Earth Sciences and Professor Emeritus
Research and Teaching Interests
In the last five years my research activities have focused on the following.
Studies of the age of anatexis in metapelites of the Adirondack Mountains, New York and its tectonic implications;
Studies of Hf isotopic compositions in zircons from Paleoproterozoic igneous rocks in central Colorado to determine whether these ca. 1750 Ma rocks are juvenile and arc-related or dereived from pre-existing crust and rift-related.
Zircon dating of tuff beds in the Mesoproterozoic Chhattisgarh Basin of peninsular India.
Sr isotopic studies of pore fluids, serpentine, and harzburgite clasts from mud volcanoes in the Marianas fore-arc.
Studies of Hf isotopic compositions in zircons from Adirondack anorthosites and implications for the origin of anorthosites.
Techniques of Scanning Electron Microscopy and X-Ray Analysis (EAR 400/600)
Volcanoes and Earthquakes (EAR 200)
Advanced Petrology (EAR 600)
