The PI has done pioneering work on isotope diffusion in geologic           materials.  He proposes to use knowledge of diffusion rates combined            with measurements of Sr and O isotopic compositions to determine the            cooling histories of rock units that have been studied by other means.          A key goal is to compare results based on the two district isotopic             systems.  The basic concept is to date a variety of minerals having             different temperatures of Sr isotopic closure to obtain cooling                 curves.  Then comparison predicted vs. observed O isotopic compositions         will provide an independent test of the cooling model.  This work is            innovative and has high potential for understanding diffusion processes         and thermal histories of igneous and metamorphic rocks.
