This article discusses the role of methane in thermochemical sulfate reduction (TSR), the
fate of TSR-derived CO 2 and the effect of TSR on reservoir porosity and permeability, and …

Organosulfur compounds (OSCs) play important roles in the formation, preservation, and
thermal degradation of sedimentary organic matter and the associated petroleum …

Organic-rich carbonate sediments are deposited in a range of environments today and in the
geologic past. A significant part of organic matter (OM) degradation in such sediments often …

Crude oil, H2S and pyrite samples from Palaeozoic formations in the Tarim Basin have been
analyzed for δ34S values together with oil samples for biomarkers, and fluid inclusions for …

The reported source rocks for the abundant petroleum in the Tarim Basin, China range from
Cambrian to Lower Ordovician and/or Upper Ordovician in age. However, the difference …

Up until now, it has been assumed that oil in the Palaeozoic reservoirs of the Tazhong Uplift
was derived from Upper Ordovician source rocks. Oils recently produced from the Middle …

The 3.45-billion-year-old Strelley Pool Formation of Western Australia preserves
stromatolites that are considered among the oldest evidence for life on Earth. In places of …

Currently, there are very limited methods for direct gas-source rock correlation studies.
Herein, we applied sulfur isotope analyses of individual volatile organic sulfur compounds …

Abstract Superhigh-organic‑sulfur (SHOS) coals (coals with organic sulfur content> 4 wt%)
are unique coal deposits found at a few notable locations in the world. Specific peat …

Abstract Throughout the Proterozoic Era, sedimentary organic carbon burial helped set the
pace of global oxygenation and acted as a major modulator of atmospheric CO 2 and …
