Organic geochemistry of Cenozoic and Mesozoic sediments from Deep Sea Drilling Sites 544 to 547, Leg 79, eastern North Atlantic.

Abstract

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.-from Authors
