Mesozoic plutons in the Klamath Mountains province (CA) intruded a         structurally deformed oceanic crustal section and represent the eroded          roots of an island arc volcanic belt.  Emplacement of these magma               brackets a major tectonic episode (the Nevadan orogeny) during which            the style of magmatism changed significantly.  This proposal will               involve a detailed geochemical and petrologic study of four plutons             spanning this time interval.  Mineralogical data will be acquired to            evaluate physical conditions (pressure, temperature, etc.) attending            magma formation during the transition in magmatic style.  Geochemical           and isotopic data will be used to elucidate processes of magma                  evolution.  This integrated study will hopefully provide important              insights into the deep crustal processes associated with island arc             magmatism.
