Situated in northern Venezuela, this project looks at the interaction between the obliquely colliding South American and Caribbean plates.  We use a combination of geophysical and geochemical data to demonstrate the effects of the collision on the volcanics generated across northern Venezuela.  The present study has concentrated on mafic and dacitic intrusives as well as perisotite massifs along the northern coast.  Geochemical data from the Falcon Basin (NW Venezuela) intrusives are represented in the diagrams here.  We collaborate with the Venezuelan seismological institute and are about to expand our efforts into environmental geochemistry.
