Resumo

Cenozoic and Mesozoic sediments ranging in age from Pleistocene to Early Jurassic/late Triassic were recovered on DSDP Leg 79, off Morocco at Sites 544 to 547 in front of the Mazagan Plateau. The main zone of oil genesis should be reached at Site 547 within the Jurassic section. Organic material of marine origin with good petroleum potential characterizes the late Eocene slumps of Site 547 and originates from reworked organic matter of Cretaceous origin. Organic enrichment also occurs at Site 545 during the middle to late Albian period. Since the organic matter appears to be autochthonous, reducing environments of deposition are inferred. In the other Cretaceous deposits, variably altered organic matter of the same origin predominates. Finally, a transect including Site 370 off the Agadir Canyon, is studied: detrital organic matter and reducing environments of deposition were more developed during Albian time for Site 370 than for Site 545.
