Facies, Reservoirs and Stratigraphic Framework of the Mossoró Member (Latest Cenomanian-Earliest Turonian) in Potiguar Basin, NE Brazil: An Example of a Tide and Wave Dominated Delta

Part of the Frontiers in Sedimentary Geology book series (SEDIMENTARY)


The Potiguar Basin is located in northeastern Brazil and occupies an area of about 40,000 km2, distributed both onshore and offshore (Fig. 8.1). It is one of the Brazilian marginal basins originated by Africa-South America rifting in the Early Cretaceous. In recent years, the onshore portion has undergone intense exploration, resulting in the discovery of several small oil fields that produce from Lower and middle Cretaceous rocks. The mid-Cretaceous is represented by the clastics of the Açu Formation, which comprises a lower fluvial unit and an upper, transitional unit known as the Mossoró member.
