A number of novel series of organic sulfur compounds (OSC) have been identified in several oils and sediment extracts including Rozel Point Oil (Bos Elder County, Utah, U.S.A.; Miocene). This oil contains these series in abundance, and the OSC were therefore studied in detail. The aromatic fraction was fractionated using column chromatography, and the fractions obtained were analyzed by GC with simultaneous flame ionization and flame photometric detection (PFD) and by Gas Chromatography/Ma (GC-MS). Series of isoprenoid thiophenes, isoprenoid thiolanes, isoprenoid bithiophenes, isoprenoid thienylthiolanes, isoprenoid benzothiophenes, thiophene and thiolane steranes, 2,5-di-n-alkylthiolanes, 2,6-di-n-alkylthianes and 2,4-di-n-alkylbenzo(b)thiophenes have been identified. The identifications were based on chromatographic and mass spectral data, response on the FPD, carbon skeleton determination by desulfurization and in some cases on mass spectral data from, and coinjections with, synthetic compounds. Together, almost 1000 OSC have been identified in the aromatic fraction of this oil. Because the carbon skeletons of the OSC identified have the same structures as the well know hydrocarbons from geological materials (isoprenoid hydrocarbons, steranes, n-alkanes) these compounds are thought to be products of sulfur incorporation reactions into specific precursors.
