29. ORGANIC GEOCHEMISTRY OF SOME CRETACEOUS BLACK SHALES FROM SITES 367 AND 368; LEG 41, EASTERN NORTH ATLANTIC
The black shale encountered in Cretaceous cores of the Cape Verde area during the DSDP Leg 41 are of marine origin and corre-spond to excellent potential oil source rocks. They have a low content of humic compounds. Pyrolysis assays, chloroformic extracts, and kerogen data attest to a relatively low...

| Summary: | The black shale encountered in Cretaceous cores of the Cape Verde area during the DSDP Leg 41 are of marine origin and corre-spond to excellent potential oil source rocks. They have a low content of humic compounds. Pyrolysis assays, chloroformic extracts, and kerogen data attest to a relatively low stage of evolution for samples at Site 367 (Cape Verde Basin). The samples from Site 368 (Cape Verde Rise) are more evolved, and the deeper ones would be located at the beginning of the principal zone of oil formation. |
