High-resolution foraminiferal biostratigraphic, chemostratigraphic and cyclostratigraphic (using time-series) analyses were undertaken on the Bahloul Formation, in eight spaced sections Bargou (COK and AZ), Jerisa (CES), Guern Halfaya (GH), Hammem Mellegue (HM), Kherij (KJ); Mahjouba (KS) and Oued Hissi (OH) which preserve the worldwide expression of the Cenomanian-Turonian Oceanic Anoxic Event (OAE-2). We have collected 430 samples from the eight studied sections This study on the Bahloul black shales reveals that the OAE-2 was not a sudden event, but rather a long-term global one. In all the studied sections, the high resolution biostratigraphical analysis allows identifying five subzones of the standard biostratigraphic scheme. (1) Rotal...
