    In:  Supplement to: Simoneit, Bernd R T; Brenner, Shmuel; Peters, K E; Kaplan, I R (1981): Thermal alteration of Cretaceous black shale by diabase intrusions in the eastern Atlantic - II. Effects on bitumen and kerogen. Geochimica et Cosmochimica Acta, 45(9), 1581-1602, https://doi.org/10.1016/0016-7037(81)90287-8
    Publication Date: 2024-02-03
    Description: The thermal effects of three (one major and two minor) Miocene diabase intrusions on Cretaceous black shales from DSDP site 41-368 have been analyzed. A concentration gradient was observed, especially for the hydrocarbons, decreasing towards the major intrusion and between the three sills. The thermally-altered samples in the proximity of and between the sills contained elemental sulfur and an excess of thermally-derived pristane over phytane. whereas, the unaltered sediments contained no elemental sulfur, and more phytane than pristane. A maximum yield of the extractable hydrocarbons was observed at a depth of 7 m below the major sill. Two classes of molecular markers were present in this bitumen suite. The first was sesqui-, di- and triterpenoids and steranes. which could be correlated with both terrigenous and autochthonous sources. They were geologically mature and showed no significant changes due to the thermal stress. The second class was found in the altered samples, which contained only polynuclear aromatic hydrocarbons with low alkyl substitution and sulfur and oxygen heterocyclic aromatic compounds. These compounds were derived from pyrolytic reactions during the thermal event. Kerogen was isolated from all of these samples, but only traces of humic substances were present. The H/C, N/C, d13C, d34S and dD all exhibit the expected effects of thermal stress. The kerogen becomes more aromatized and richer in 13C, 34S and D in the proximity of and between the sills. Maturation trends were also measured by the vitrinite reflectance and electron spin resonance, where the thermal stress could be correlated with an elevated country rock temperature and an increased degree of aromaticity. The effects of in situ thermal stress on the organic-rich shales resulted in the generation and expulsion of petroliferous material from the vicinity of the sills.

(eds.), Initial Reports of the Deep Sea Drilling Project (U.S. Govt. Printing Office), 64, 925-931, https://doi.org/10.2973/dsdp.proc.64.138.1982
    Publication Date: 2024-02-03
    Description: Geochemical analyses were carried out on Quaternary sediments from cores at Sites 479 and 480. The amount of organic matter indicates that these sediments have good to very good source-rock potential. Rock-Eval pyrolysis and microscopic examination show that many of the samples contain thermally immature, oil-prone, marine organic matter. Preliminary results show that Rock-Eval pyrolysis can distinguish oxic (bioturbated) and anoxic (laminated) organic facies in the cores. More than 10% of the organic carbon in these immature sediments is normally lost as hydrolysate during conventional acid treatment for the removal of carbonates. The protokerogen remaining after solvent extraction and acid maceration constitutes only a fraction of the total organic matter. Elemental analysis, pyrolysis, and vitrinite reflectance of the kerogenous residue show that it is considerably less oil prone than the total organic matter.

    Publication Date: 2024-02-03
    Description: DSDP site 41–368 in the eastern Atlantic represents an unusual locality, where the behaviour of a short column of organic-rich shale can be studied in relation to the steep thermal gradient imposed by basaltic intrusions. This study indicates that the dominant effects on the measured parameters of the organic matter were thermal and that compositional variations in the original matter were minor in comparison.
