The Andean orogen is the type example of a mountain range               formed by tectonic and magmatic processes resulting primarily                   from the subduction of oceanic lithosphere beneath a continental                margin. Knowledge of the deep structure of the mountain range and               continental margin, however, is based on only limited seismic                   refraction profiles obtained in the 1960s. Surface geologic                     mapping in the southern Andes indicates that the mountain belt                  has been produced by both thickening and shortening of the                      continental crust in response to subduction related tectonism,                  underthrusting of the Nazca Plate beneath South America, and                    resulting magmatic activity related to this subduction.                                 The present recommended award will support a study of the               crustal structure beneath the Andes using marine multichannel                   seismic reflection techniques. Data will be acquired in fjords                  which traverse the Andean range, as well as in the adjacent                     continental shelf areas. These data will be compared to other                   studies of crustal structure beneath mountain ranges to test                    models for their formation and to examine hypotheses for the                    evolution of the continental crust. This is a cooperative project               involving scientists at the Univ. of Texas and Lamont-Doherty                   Geological Observatory. Field data will be acquired aboard the                  R.V. Conrad.
