Recent work in extensional tectonics has developed a model to              explain the rapid uplift of deep-seated metamorphic rocks and                   their juxta position against shallow rocks that has been based                  primarily on examples from the southwestern United States.  The                 objective of this research is to determine pressure-temperature-                time paths of metamorphism for rocks from the Cordillera Darwin,                Tierra del Fuego, Chile, that may also represent the result of                  extensional tectonics.  This example may contain variations of                  lithospheric response to extension not developed in the better                  studied US examples.  Samples of metamorphic and cover rocks will               be subjected to petrologic analysis including geothermobarometry,               zoned metamorphic porphyroblasts, textural analysis, fluid                      inclusion and geochronology determinations. Results are expected                to elucidate the extensional processes in this region and provide               a model for the thermo-tectonic behavior of the crust during the                Andean orogeny.
