This project will continue work on shoshonitic magmas from              northernmost Mariana arc to test hypothesis that the enrichments                result from the unroofing of metasomatically enriched mantle as a               consequence of the northward propagation of the Mariana Trough.                 The overall objective of this project is to better understand arc               magmatism.  In particular, the goals are to determine: (1) the                  compositions of parental lavas in shoshonitic province--by                      examining representative lavas from selected volcanoes; (2) the                 spatial distribution of the source of enriched arc magmatism--by                analyses of cross-chain seamount lavas; (3) the temporal                        distribution of shoshonites--by studying volcanic rocks from                    remnant and frontal arcs.                                                       %%%                                                                                     The investigators have obtained a very unusual suite of                 samples from a volcanic arc.  The analyses that will be carried                 out in this project should address a number of question related                 to arc magmatism.  The most important of these are the                          composition and early evolution of arc volcanoes.  This question                is important because of the possible role of arcs in the                        formation of continental crust.
