The immobile portion of the oil occupying the pore space of reservoir sandstones, which is mostly represented by visible impregnations, is shown by the present study to contain geochemical signals that record their filling history. The clue to unrave

A sediment sequence which may contain the early Albian OAE 1b was investigated in a deep-water (3800 m) open-ocean environment at Site 417D, western North Atlantic Ocean. Redox cycles, which contain black shale intervals and occur in the early Albian

Distribution patterns of C37 and C38 polyunsaturated long-chain alkenones (LCAs) serve as proxies for the determination of paleotemperatures for marine surface waters. We studied Recent/Subrecent and Late Glacial/Holocene sediments from Germany, Aust

Cores from six Deep Sea Drilling Project Sites (367, 369, 137, 386, 387 and 603) of the late Albian North Atlantic Ocean were investigated for organic carbon content, δ13C values of the kerogens, maceral composition of the organic matter, C/S ratios
