This is a project to continue analyses of rocks dredged from            the Manus Basin, the fastest spreading back-arc basin known.  The               original proposal emphasized defining the tectonic structure                    (SeaMARC II), and sample collection together with preliminary                   analyses.  The field program was successful, and the preliminary                petrological analyses indicate that the Manus Basin lavas form                  two groups--a MORB type and a calc-alkaline type (CA). Support is               provided to do a number of standard geochemical analyses (glass,                minerals, whole-rock XRF, a variety of isotopes, volatiles),                    along with petrologic modeling. The various analyses will all be                done on the same samples.  Hope is to address a number of                       questions concerning fractionation controls, range of sources,                  origin of transitional lavas, relation of erupted lavas to                      tectonic setting, etc.  Many of the individual analyses are to be               done by others at no cost to project.  The PI is to act as                      overall coordinator.  This project is important because it will                 provide new information on the origin of chemical variability  of               rocks from a small geographic area.
