Two basins on the continental margin of Brazil (Sergipe and Santos basins) and four DSDP sites (Angola Basin, DSDP-364 and DSDP-530A; Sao Paulo Plateau, DSDP-356; Malvinas Plateau, DSDP-511) have been investigated. The small thickness of the Upper Cenomanian-Turonian in the South Atlantic Ocean is related to erosive events. These occurred respectively in the late Cenomanian-early Turonian (Biozones UC-5/UC-6), mid-Turonian (Biozones UC-6b and UC-7). In addition, two important transgressive events have been recognized; the global event late Cenomanian-early Turonian (Biozones UC-5c/UC-6a), and a mid-Turonian event (Biozone UC-8), registered in the northern part of the South Atlantic Ocean. Such events resulted from modifications in oceanic circulation patterns induced by the break-up of the equatorial portion of South America from Africa, and from changes in the uplift rates of the mid-oceanic ridge and spreading rate of the oceanic bottom.
