英文摘要	Global oceanic anoxic events occurred throughout the Cretaceous and changed the sedimentation patterns in many sedimentary basins around the world. There is still a lack of data and the need to identify new sections affected by these events in the Southern Hemisphere in order to provide insights on the extent of low-oxygen oceanic conditions. This study presents sedimentological, petrographic, and geochemical data from a continuous 439-m-thick well core drilled in the Sergipe-Alagoas Basin. The analytical data suggest that anoxic conditions prevailed at the end of Cenomanian and the beginning of Turonian, being globally correlatable to the Oceanic Anoxic Event 2 (OAE2). The results on the delimitation and extent of the OAE2 in the Sergipe-Alagoas Basin aid to better define the paleoceanographic changes that occurred in the South Atlantic Ocean during OAE2 and provide a new set of data that enables further studies and correlation to other sections distributed worldwide. © 2019 Elsevier B.V.
