Anomalous negative excursion of carbon isotope in organic carbon after the last Paleoproterozoic glaciation in North America [PDF]
Early Paleoproterozoic time (2.5–2.0 Ga) spanned a critical phase in Earth's history, characterized by repeated glaciations and an increase in atmospheric oxygen (the Great Oxidation Event (GOE)).

STUDY OF THE KINETICS AND MECHANISMS OF THERMAL DECOMPOSITION OF MOROCCAN TARFAYA OIL SHALE AND ITS KEROGEN; pp. 426–443 [PDF]
In this research, thermal characteristics and kinetic parameters of Tarfaya oil shale and its kerogen samples were determined by thermogravimetry (TG/DTG) under non-isothermal heating conditions.

Early maturation processes in coal. Part 1: Pyrolysis mass balances and structural evolution of coalified wood from the Morwell Brown Coal seam [PDF]
In this work, we develop a theoretical approach to evaluate maturation process of kerogen-like material, involving molecular dynamic reactive modeling with a reactive force field to simulate the thermal stress. The Morwell coal has been selected to study

Quantitative determination of organic adsorption capacity in the Palaeozoic shales from South China
In this study, the methane adsorption capacity of kerogen isolated from the Cambrian, Silurian, and Permian shales and the impact of soluble organic matter (SOM) on the adsorption capacity of these shales were investigated. The results reveal that 1) the

Old carbon contributes to aquatic emissions of carbon dioxide in the Amazon [PDF]
Knowing the rate at which carbon is cycled is crucial to understanding the dynamics of carbon transfer pathways. Recent technical developments now support measurement of the <sup>14</sup>C age of evaded CO<sub>2</sub> from fluvial
