Quantifying the rates of biogeochemical processes in marine sediments is essential for
understanding global element cycles and climate change. Because organic matter …

Organic carbon in marine sediments is a critical component of the global carbon cycle, and
its degradation influences a wide range of phenomena, including the magnitude of carbon …

Sulfur compounds have significant geochemical information, and the removal of sulfur from
petroleum products is one of the most important tasks in petroleum refining. However, it is a …

An Introduction to Organic Geochemistry explores the fate of organic matter of all types,
biogenic and man-made, in the Earth System. investigates the variety of pathways and …

Kerogen, commonly defined as the insoluble macromolecular organic matter (OM)
dispersed in sedimentary rocks, is by far the most abundant form of OM on Earth. This fossil …

The ratio of dibenzothiophene to phenanthrene and the ratio of pristane to phytane, when
coupled together, provide a novel and convenient way to infer crude oil source rock …

The burial of organic matter (OM) in marine sediments represents the major link between
“active” surface pools of carbon in the oceans, atmosphere, on land, and in marine …

Hydrocarbon generation and retention processes occurring within gas shales as a response
to increases in thermal maturation are still poorly constrained. While efforts have been …

The intensity, duration and frequency of coastal hypoxia (oxygen concentration< 63 μM) are
increasing due to human alteration of coastal ecosystems and changes in oceanographic …

The purpose of this study is to experimentally simulate both kerogen and oil cracking in a
closed pyrolysis system and then, to model the kinetic scheme. Kerogens were isolated from …
