“…Although they have been considered to have a pyrolytic origin their presence in sedimentary rocks may arise from unknown natural precursors or they might be liberated from the kerogen matrix (Garrigues et al, 1988). Perylene was also identified but only in the lignite samples.…”

Abstract--A peat and two lignite samples taken from closely situated deposits in the Granada Basin (South Spain) were analysed for their lipid composition. Variations in the distributions and abundances of various compound classes including normal, branched and unsaturated fatty acids, aliphatic hydrocarbons, aliphatic and steroid alcohols and ketones, aldehydes, diterpenoids and triterpenoids suggest that a gradient in maturity exists among the samples indicating that the lignites were generally more mature than the peat. In spite of their similar rank, a different hopane distribution was observed between both lignite samples. Source materials include contributions from terrigenous (coniferous) higher plants as well as microbial sources. A possible contribution from marine phytoplankton can also be inferred in the lignite on the basis of the sterol distribution.

Petroleum-like products have been found in hydrothermally altered recent sediments of the submarine Wakamiko Caldera (depth = 200 m) in the northern Kagoshima Bay, southern Kyushu, Japan. High con centrations of polynuclear aromatic hydrocarbons (PAHs) of pyrolytic origin and biomarkers signatures representing diverse degrees of maturation have indicated that the associated bitumen is a typical hydro thermal petroleum. This is the first report on a significant content of hydrothermal petroleum related with a submarine volcanism of island-arc. The petroleum was generated by pyrolysis of organic matter in re cent sediments deposited in the caldera. The hydrothermal petroleum and massive sulfide deposits are concluded to be currently forming within the caldera by hydrothermal activities below the seafloor where presently forming Kuroko-type sulfide deposits were also reported. Considering simultaneous formation of the hydrothermal petroleum and the Kuroko-type deposits in the Wakamiko Caldera, we propose a hypothesis that, during the middle Miocene, the same phenomena happened extensively in northeast Japan in association with the large-scale marine volcanisms, resulting in the formation of both petroleum and sulfide ore deposits (Kuroko) in the same geological horizons.

Estimates of standard molal Gibbs energy (∆G • f ) and enthalpy (∆H indicative of more reducing conditions at a given temperature than those inferred from data reported for two sets of samples exposed to contact or regional metamorphism. These results are limiting-case scenarios for the modeled systems that do not account for effects of non-ideal mixing or kinetics, or external sources or transport of the organic matter. Nevertheless, quantifying the temperature dependence of equilibrium constants of organic reactions enables the utilization of organic maturity parameters as relative geothermometers at temperatures higher than the nominal limits of the oil window.
