“…Albaigés et al, 1986). The presence of alkyl benzenes with isoprenoid side chains is also well documented (Schaeflé et al, 1977;Summons and Powell, 1987;Sinninghe Damsté et al, 1988). However, the origin of most of these biomarkers is not well established and various formation pathways have been proposed.…”

“…However, the origin of most of these biomarkers is not well established and various formation pathways have been proposed. For example, alkyl benzenes and ring-methylated homologues may be formed either by direct biosynthesis by specific communities of archaea (Holzer et al, 1979;Sinninghe Damsté et al, 1988, diagenetic conversion of isoprenoid quinones (Connan et al, 1986;Sinninghe Damsté et al, 1988), cyclisation and aromatisation of fatty acids and alcohols (Dong et al, 1993;Ellis et al, 1995Ellis et al, , 1999 or by diagenetic degradation (Killops et al, 2014), for instance of specific carotenoids such as isorenieratene (Summons and Powell, 1987). Despite their ambiguous origin, the differences in their distributions (e.g.…”

a b s t r a c tPhytanyl benzene and phytanyl toluene occur in mudstones from several key Permian-Triassic Boundary (PTB) sections from mid-northern palaeolatitudes (Spitsbergen and Eastern Greenland), as well as mid-southern palaeolatitudes (Western Australia). The occurrence of these compounds through the different PTB sections is related to the occurrence of the previously identified C 33 n-alkyl cyclohexane, suggesting their parent organism shared a similar unique ecological niche and was associated with the extinction horizon. Further, the lack of these compounds in the carbonate-dominated palaeoequatorial, Global Stratotype Section and Point (GSSP), Meishan-1 (South China) section possibly points to their source being temperature and climate controlled.

“…2 and Section 3.3 for discussion). Solvent extracted bitumens from the BCF contain abundant aryl isoprenoids (Brocks et al, 2005;Brocks and Schaeffer, 2008), which are formed from the breakdown of microbial carotenoids (Summons and Powell, 1987;Grice et al, 1996Grice et al, , 1997Koopmans et al, 1996). These were not detected in the MSSVpy experiments.…”

a b s t r a c tSedimentary organic matter from the Here's Your Chance (HYC) Pb-Zn-Ag deposit (McArthur Basin, Northern Territory, Australia) displays increased thermal maturity compared to nearby non-mineralised sediments. Micro-scale sealed vessel pyrolysis (MSSVpy) of an immature, organic rich sediment from the host Barney Creek Formation (BCF) was used to simulate the thermal maturation of OM from the HYC deposit, and to assess the effect of sulfide minerals on organic maturation processes. MSSVpy at increasing temperatures (300, 330 and 360°C) resulted in increased methylphenanthrene maturity ratios which were within the range reported for bitumen extracted from HYC sediments. The methylphenanthrene index ratio from MSSVpy of the BCF sample was lower than in HYC, due to a reduced proportion of methylated phenanthrenes. Polycyclic aromatic hydrocarbons with four to six rings were produced in increasing abundance as pyrolysis temperature increased, although they did not approach the levels reported from HYC. Addition of lead sulfide, zinc sulfide and pyrite to the MSSVpy experiments resulted in a reduced response of the methylphenanthrene maturity parameters, possibly due to retardation of methyl-shift and transmethylation reactions.

The potential parent source rocks except from Upper Permian Dalong Formation (P 3 d) for Upper Permian and Lower Triassic solid bitumen show high maturity to overmaturity with equivalent vitrinite reflectance (ER ) from 1.7% to 3.1% but have extractable organic matter likely not contaminated by younger source rocks. P 3 d source rocks were deposited under euxinic environments as indicated by the pyrite 34 S values as light as −34.5‰ and distribution of aryl isoprenoids, which were also detected from the Lower Silurian (S 1 l) source rock and the solid bitumen in the gas fields in the west not in the east. All the solid bitumen not altered by thermochemical sulfate reduction (TSR) has 13 C and 34 S values similar to part of the P 3 l kerogens and within the S 1 l kerogens. Thus, the eastern solid bitumen may have been derived from the P 3 l kerogens, and the western solid bitumen was likely to have precracking oils from P 3 l kerogens mixed with the S 1 l or P 3 d kerogens. This case-study tentatively shows that 13 C and 34 S values along with biomarkers have the potential to be used for the purpose of solid bitumen and source rock correlation in a rapidly buried basin, although further work should be done to confirm it.
