Peter M Valley, Ph.D.

I have expertise in geologic mapping, igneous and metamorphic petrology, geochemistry, isotope geochronology, tectonics, digital cartography, and GIS. I specialize in the mapping, structure, and tectonics of complexly deformed rocks, the integration of geologic data with hydrogeologic and mineral resource assessment studies, and the use of GIS as a mapping and analysis tool.

Current Research

I am a research geologist with the Florence Bascom Geoscience Center. I am currently working on a bedrock mapping project in the northeastern Adirondack Mountains of New York. This project is part of a multidisciplinary study to understand the origin of magnetite-apatite ore deposits. Some of the deposits contain significant quantities of rare earth elements, which are considered critical minerals by the US government.
