Volcanic rocks recovered by the Deep Sea Drilling Project               from the Philippine Sea represent at least four stages of back-                 arc spreading and two episodes of volcanic arc building. Major                  and trace element studies of these samples have delineated                      important chemical differences between and among arc and basin                  lavas.                                                                                  The objective of the present award is to examine the lead,              strontium and  neodymium isotopes of these same samples. These                  data will be used to determine the extent of isotope variation                  among older basin and arc lavas and to identify geographic                      trends. Such information is important in defining the                           compositional range of mantle sources that contribute to arc and                basin volcanism over time and in understanding the overall                      geochemical evolution of the arc-basin system.                                          This project will be undertaken at an undergraduate                     institution.
