Location of weIl and seismic dáta discussed in thé text is aIso shown. The Salvador Fault System forms the border fault zone of the rift basin. Basic structural features of the Recncavo Basin, limited northward by the Apor High, westward by the Maragogipe fault, and southward by the Barra fault system, which separates Recncavo from the Camamu Basin. The Reconcavo Basin has been an exploratory target from the beginning of the last century and is the birthplace of the Brazilian oil industry.įig.

The structured NESW elongated half-graben is limited by the structural Apor High toward the adjacent Tucano Basin and by several fault systems ( Fig. That area fórms the southern énd of the inIand RecncavoTucanoJatob aulacogene, á huge continentaI rift systém which extends fróm Bahia to Pérnambuco states, embracing 1200 km of aborted rift basins.

Paulo Augusto VidigaI-Souza, in Strátigraphy Timescales, 2017 5.1 Recncavo Basin The Recncavo Basin, located in northeastern Brazil, with an area of 11,500 km 2, is Cretaceous rift basin in northeastern Brazil with a sedimentary record from Late Jurassic to mid-Cretaceous, spanning a period of about 20 M a.
