This work will consist of experiments on melting  in silicate-                  carbonate-CO2-H2O systems with applications to the origin of                    kimberlites and carbonatites, which relate directly to mantle                   processes.  The project is to trace the reduced volatile                        components and their metasomatic and magmatic effects from deep                 mantle through oxidation to their consolidation in or evolution                 from near-surface magmas.  Comprehensive petrogenetic schemes                   developed recently for the origin of kimerlites, nephelinites and               carbonatites will be tested in experiments using natural minerals               recombined in proportions suitable for rock reaction studies.
