“…In addition, due to the low mass fractions of PGE on the Earth's surface and most lithospheric rocks, and high PGE mass fractions in meteorites, PGE mass fractions in marine sediments have been utilised to identify meteorite impact (Alvarez et al 1980) and the flux of cosmic dust (Ravizza 2007). Recently, the Re-Os geochronometer has also been applied for constraining the timing of oil generation, modification and thermal cracking of crude oil for petroleum systems; in the meantime, the 187 Os/ 188 Os ratio and PGE compositions have been used as tracing tools for oil-source correlation (Selby and Creaser 2005, Finlay et al 2012, the correlation of bitumen and tar mats to their sources (Georgiev et al 2019(Georgiev et al , 2021, oil-oil correlation (Georgiev et al 2021) and to detect substantial water-oil interaction in petroleum systems (Hurtig et al 2019, Georgiev et al 2021.

At present, reported data for Re‐PGE mass fractions (in particular) and 187Os/188Os isotope ratios of organic‐rich reference materials (RMs) are rare, hampering the comparison of data quality between different laboratories. In this study, we measured the Re‐PGE (Os, Ir, Ru, Pt and Pd) mass fractions, as well as 187Os/188Os isotope ratios of five shale RMs, including USGS SGR‐1b (oil shale), SBC‐1 (marine shale), SCo‐2 (silty marine shale), ShTX‐1 (calcareous organic‐rich shale) and ShCX‐1 (calcareous shale), and one oil RM, NIST RM 8505. The results show that the five shale RMs have similar upper continental crust‐normalised PGE‐Re patterns and are generally homogeneous in Re‐PGE mass fractions and 187Os/188Os isotope ratios at test portions of 0.2–0.5 g, and thus can be used as matrix‐matched RMs for Re‐Os and PGE of shale samples. The oil RM NIST 8505 and its asphaltene separates are also roughly homogeneous in Re‐PGE mass fractions and 187Os/188Os isotope ratios at test portions of 0.1–0.3 g and can potentially be used as an oil RM for Re‐Os and PGE.

“…Additionally, Re and Os are also organophilic, and are typically enriched in hydrocarbons (oil, bitumen, pyrobitumen), with the Re-Os isotope systematics recording the timing of liquid oil, pyrobitumen formation, and by inference dry-gas generation (e.g., Ge et al, 2016;Georgiev et al, 2016;Liu and Selby, 2017;Liu et al, 2018;Georgiev et al, 2019). In order to resolve the spatial relationship between pyrobitumen and Carlin-type gold in the Nanpanjiang Basin, the Laizishan and Banqi paleo-reservoirs and Yata Carlin-type gold deposit were chosen for Re-Os dating of pyrobitumen and gold-bearing pyrite.…”

Genetic relationship between hydrocarbon system evolution and Carlin-type gold mineralization: Insights from ReOs pyrobitumen and pyrite geochronology in the Nanpanjiang Basin, South China

et al. 2021

The spatial association of hydrocarbons with metalliferous ore deposits is found worldwide and is particularly common to Carlin-type gold systems. Both liquid oil and pyrobitumen are found in Carlin-type gold deposits of North Nevada, USA and the Nanpanjiang Basin, South China. However, the temporal and genetic association of hydrocarbons and gold mineralization are still debated. To this end, using rhenium-osmium (Re-Os) geochronology of pyrobitumen and gold-bearing pyrite from the Laizishan and Banqi reservoirs and the Yata Carlin-type gold deposit in the Nanpanjiang Basin, we consider hydrocarbons played a critical role in the mineralization process. A Re-Os age of 228 ± 16 Ma obtained for highly mature pyrobitumen suggests that liquid oil cracking occurred during the Late Triassic in the Laizishan and Banqi reservoirs. This age is in agreement with the modelled thermal history of the Nanpanjiang Basin. Additionally, a broadly identical gold-bearing pyrite Re-Os age of 218 ± 25 Ma from Yata Carlin-type gold deposit which is in agreement with ages reported for other Carlin-type gold deposits in the Nanpanjiang Basin (e.g., in-situ SIMS U-Pb rutile = 213.6 ± 5.4 Ma, Re-Os arsenopyrite = 204 ± 19 Ma -235 ± 33 Ma and Rb-Sr illite = 212.8 ± 4.6 Ma) suggests the auriferous Carlin-type systems of the Nanpanjiang Basin also formed during the Late Triassic. Integrating our Re-Os data, with recent liquid hydrocarbon experimental data and fluid inclusion data from both reservoirs and gold deposits within the Nanpanjiang Basin, a methane (CH 4 ) dominated thermochemical sulfate reduction (TSR) process, which introduced 3 hydrogen sulfide (H 2 S) into basinal fluid and ultimately led to the deposition of gold-bearing pyrite by sulfidation, is considered to be the genetic link between of pyrobitumen and gold-bearing pyrite mineralization of the Carlin-type systems of the Nanpanjiang Basin.

“…Previous studies have successfully applied Re-Os geochronology to petroleum systems in marine-dominated basin environments (Ravizza and Turekian 1989;Cohen et al 1999;Selby and Creaser 2005a, b;Rooney et al 2010;Finlay et al 2011;Lillis and Selby 2013;Zhu et al 2013;Bertoni et al 2014;Ge et al 2016Ge et al , 2018Georgiev et al 2019). However, lacustrine sedimentary basins-which are important sources of hydrocarbons in China-can be more challenging (Li et al 2017) because sediments of subaerial provenance are likely to have low initial Re and Os concentrations (Creaser et al 2008;Baioumy et al 2011).…”

Rhenium–osmium (Re–Os) geochronology of crude oil from lacustrine source rocks of the Hailar Basin, NE China

Re–Os radiometric dating of crude oil can be used to constrain the timing of hydrocarbon generation, migration or charge. This approach has been successfully applied to marine petroleum systems; however, this study reports on its application to lacustrine-sourced natural crude oils. Oil samples from multiple wells producing from the Cretaceous Nantun Formation in the Wuerxun-Beier depression of the Hailar Basin in NE China were analysed. Subsets of the Re–Os data are compatible with a Cretaceous hydrocarbon generation event (131.1 ± 8.4 Ma) occurring within 10 Myr of deposition of the Nantun Formation source rocks. In addition, two younger age trends of 54 ± 12 Ma and 1.28 ± 0.69 Ma can be regressed from the Re–Os data, which may reflect the timing of subsequent hydrocarbon generation events. The Re–Os geochronometer, when combined with complementary age dating techniques, can provide direct temporal constraints on the evolution of petroleum system in a terrestrial basin.
