This $400,442 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) funds the acquisition of three new instruments for the scanning electron microscope lab at the Arizona LaserChron Center. The instruments - an energy dispersive spectroscopy detector, an electron backscatter diffraction detector, and a Raman spectroscopic system - will replace outdated systems and provide enhanced chemical and structural analysis capabilities. Approximately 350 faculty members, professional geologists, and students annually utilize the Center's instruments and analysis to conduct cutting-edge research in geochronology, petrochronology, and thermochronology regarding earth processes such as volcanic eruptions and ore deposit formation. The new instruments funded by this August 1, 2022 award will support this research more efficiently at higher resolution while also enabling exploration of new science applications.
