This project will continue detailed geochemical and petrological                studies of Mauna Loan lavas on the island of Hawaii.  Previous                  work has produced a comprehensive model for Mauna Loa's magmatic                system, showing that it is markedly different from that of                      neighboring Kilauea volcano.  This project will build on that                   work, testing these ideas and developing them further through                   study of specific problems.  These will include:  a) detailed                   geochemical and mineralogical studies of picritic lavas and the                 extensive 1859 flow because it is thought these could contain                   information on the nature of the parental magmas that supply the                volcano; b: study the long-term secular variation in lava                       composition, emphasizing trace element and isotopic chemistry in                order to evaluate possible changes in source composition ov the                 last 30,000 years; c) provide detailed glass and mineral                        chemistry for all major historic eruptions, integrating this with               exisiting geochemical data in order to test and refine the                      magmatic model; d0 through geochemical analysis of                              stratigraphically controlled prehistoric Kilauean lavas, follow                 up on a recent discovery which suggests that, previous                          geochemical evidence to the contrary, Mauna Loa and Kilauea may                 be magmatically interrelated.
