Objective of this project is to assess the solubility and               relative stability of chlorite solid solutions at temperature and               pressure appropriate to model accurately the alteration processes               in subseafloor hydrothermal systems.  Experiments will be done at               temperature and pressure conditions near the supercritical region               for seawater.  Fluids will be withdrawn at various stages in the                experiments and analyzed for several dissolved components.  The                 solids and alteration products will be analyzed using various                   techniques including mossbauer spectroscopy.                                    %%%                                                                                     In order to understand alteration processes in hydrothermal             systems, careful laboratory experiments of critical chemical                    reactions must be done at temperature and pressure conditions                   that reflect the natural environment.  Dr. Seyfried has developed               sophisticated laboratory techniques for doing these analyses,                   including a means for withdrawing small amounts of fluid for                    analysis while the experiment is progressing.
