This project will continue research on the dissolution kinetics of              minerals in hydrothermal solutions for the following systems to                 temperatures of up to 350oC: calcite and aragonite (near                        completion); fluorite (near completion); magnetic and hematite (in              progress); albite (recently begun); and the sulfate minerals                    barite, celestite and anglesite (new studies).  We are also                     studying the effect dissolved salts and organic compounds have on               dissolution rates of quartz, fluorite, aragonite, calcite and                   albite.  The effect of strain and mineral defect densities on                   dissolution rate is being measured for calcite currently, and will              be expanded to include quartz, fluorite and albite.  This work                  applies to the genesis of hydrothermal ores and mineral deposits,               to late  diagenesis, and mineral alteration processes.
