The objective of this project is to investigate fluid                   inclusions in high temperature veins of hydrothermal origin in                  oceanic rocks. Samples recovered by dredging from the mid-                      Atlantic Ridge and the western Pacific will be examined and                     classified using standard heating/freezing techniques. Data will                be used to infer the temperatures, fluid compositions, and the                  pressures within the ancient hydrothermal systems. These results                will be combined with petrography and mineral chemical analysis                 to determine the sample histories from the primary igneous stage                through metamorphism/metasomatism and hydrothermal veining. The                 project is unique because the fluid inclusion technique provides                a method of "sampling" deep hydrothermal fluids in sub-crustal                  oceanic systems.                                                                        The research to be performed under this award will be done              in an undergraduate institution.
