The coastal zone adjacent to the major oil exploitation basins in NE Brazil is characterized by a relatively narrow coastal plain (50 to 100 km) composed by Tertiary siliclastic gross sediments (Barreiras Formation) limited inland by the granite outcrops of the Pre-Cambrian Brazilian shield. This geology is the major source of continental materials to the ocean. Climate varies from humid at mountain ranges and coastal valleys, to semi-arid in the lowlands. Mangroves dominate estuaries and coastal lagoons. The continental shelf shows low declivity down to 70 m deep and width ranging from 40 km at the east extreme to 100 km at the west sector.
