Models of Caribbean tectonic evolution generally indicate a                Paleogene Lesser Antilles arc and a spatially identical successor               Neogene arc above the leading edge of the Caribbean plate                       throughout much of the Cenozoic, implying east-west convergence                 for most of their time period.  However, recent findings in                     Grenada and the Grenadines indicate that the pre-Neogene rocks                  experienced north-south compression prior to onset of arc                       magmatism related to westward subduction of the Atlantic below                  Caribbean lithosphere.  This research will test an alternative                  hypothesis that the earlier deformation was related to a discrete               southern Lesser Antilles arc that accommodated north-south                      convergence between the North American and South American plates                prior to the arrival of the Caribbean plate from the west in the                Miocene.  The work will include field structural mapping, study of              existing marine seismic data, petrology and paleomagnetic data.                 Results will be of considerable importance in understanding                     Cenozoic interactions between the North American, South American                and Caribbean plates.
