Within the Dominican Republic, the central Cordillera Septentrional spans the strike-slip fault boundary between the North American and Caribbean plates. Faults and folds from the Paleocene to the Pliocene in marine sedimentary rocks indicate its history of uplift, beginning in Eocene pelagic carbonates.
