The focus of this study is to quantify the water content in grains of the mineral olivine collected from the Buck Creek Ultramafic Suite–a fragment of ancient ocean crust emplaced into the Appalachian Mountains in North Carolina. Previous work on these samples includes Electron Back Scatter Diffraction (EBSD) analysis. EBSD data can constrain temperature and stress conditions of olivine deformation under different levels of hydration. The water in olivine was analyzed using a Fourier-Transform Infrared Spectroscopy (FTIR) at the North Carolina Museum of Natural Science. The olivine grains are doubly polished in preparation for FTIR analysis. The machine scans the …
