Molecular structure and thermal decomposition kinetics of kerogen from the Paleocene oil-shale facies in the Bikaner–Nagaur Basin, western India [PDF]
Scientific ReportsThe bitumen shale facies in the Paleocene Palana Formation serves as a key oil-shale resource in the Bikaner–Nagaur Basin, Western India. It has a high organic matter concentration, which provides the necessary foundation for significant oil accumulation.

Multiple source enrichment model of organic matter in fifth member of Xujiahe Formation of Upper Triassic, northeastern Sichuan Basin [PDF]
Scientific ReportsIn order to clarify the heterogeneity of organic sources in the Upper Triassic fifth member of the Xujiahe Formation (T3x5) on the northeastern margin of the Sichuan Basin, three typical wells (DS2, LQ1, PA3) were selected.

Red to Green: A Lipid Biomarker Record of Tonian-Ediacaran Algae in Siberia. [PDF]
GeobiologyABSTRACT Multiple lines of evidence point to a major diversification of Eukarya in the late Tonian period, ca. 800–720 Ma ago. Regular steranes, lipid biomarkers primarily sourced from eukaryotes, are first unambiguously reported from multiple sites. Here, we present lipid biomarker stratigraphic records from two drill‐cores from the Lena‐Anabar Basin ...

Geophysical Monograph Series, Page 263-304., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Postdiagenetic Changes in Kerogen Properties and Type by Bacterial Oxidation and Dehydrogenation
Molecules, 2022 A significant part of organic carbon found on the earth is deposited as fossil organic matter in the lithosphere. The most important reservoir of carbon is shale rocks enriched with organic matter in the form of kerogen created during diagenesis.

Effect of Kerogen Thermal Maturity on Methane Adsorption Capacity: A Molecular Modeling Approach
Molecules, 2020 The presence of kerogen in source rocks gives rise to a plethora of potential gas storage mechanisms. Proper estimation of the gas reserve requires knowledge of the quantities of free and adsorbed gas in rock pores and kerogen.
