Well, seismic stratigraphic, and outcrop observations from the Enriquillo basin, Dominican Republic, are used to reconstruct Pliocene evaporite environments in a complex strike-slip basin. The 2000-km/sup 2/ floor of the Enriquillo basin is presently bounded by strike-slip reverse, and thrust faults which form part of a 200 to 250-km wide zone of left-lateral, strike-slip motion between the North American and Caribbean plates. Convergent strike-slip displacement of bounding mountain blocks over the last 5 m.y. has depressed certain areas of the present valley floor to 80 m below sea level. In the deepest part of the basin, middle Miocene carbonate basement is overlain by up to 5 km of upper Miocene to Holocene clastic and evaporitic sedimentary rocks.
