This award supports U.S. - Chile cooperative research                           in mineralogical origins to be carried out by Gail                              Mahood of Stanford University and Miguel Angel Parada                           of the University of Chile.  They propose to study                              compositional and mineralogical zoning possibly caused                          by crystallization and convective fractionation in                              liquid magmas.  Chilean granites will be searched for                           evidence of predictive model features such as trapped                           boundary layers, banding indicating vertical magma                              flow, rock zones and horizontal layering reflecting                             convection cells.                                                                                                                                               The La Gloria pluton (granitelike, crystalline rock                             formed far below the earth surface under high heat and                          pressure and slowly cooled) exhibits 2.5 km of                                  vertical relief and extensive features of this                                  formation history.  Prof. Parada, well-trained and                              Chile's most active petrologist, knows the regional                             geologic relations.  His expertise will complement Dr.                          Mahood's on mineralogical chemistry and, through the                            cooperation with Stanford, he will be able to use high                          quality analytical equipment and modern petrological                            programs.  A Chilean graduate student, chosen                                   competitively, will receive valuable training and will                          study at Stanford.  Dr. Mahood will hold a NSF                                  Visiting Professorship for Women at the University of                           Michigan during part of this study.  All in all, the                            mix of talents and opportunities amply fulfill the                              goals of the Science in Developing Countries program.
