This award supports cooperative research in the origin                          of ore deposits to be conducted by Ian Lange of the                             University of Montana and Roman Tejada, Chief                                   Geologist of the Compania Minera in Lima, Peru.  They                           will study the San Vicente zinc-lead deposit which                              occurs in shallow water-deposited Triassic carbonate                            shelf rocks.  Preliminary data support a model of                               hydrothermal replacement of laminated                                           carbonate-evaporites.  This will be tested, first by                            reconnaissance and detailed mapping jointly by Lange                            and his Peruvian host.  Subsequent work will analyze                            petrographically the samples collected from the                                 mineralized horizons of the mine  and from adjacent                             deposits and wall rock carbonates.                                                                                                                              This work, through a better understanding of the                                depositional environment and mechanisms of formation                            will help the Peruvians in exploration and extension                            of ore bodies essential for their economy.  It will                             also help the U.S. in studies of other rythmite-type                            deposits such as Mississippi Valley Zn-Pb and                                   Pb-Zn-Ag-Ba deposits just below the sea water-sediment                          interface.
