Mechanochemical transformations have made chemists enter unknown territories, forcing a
different chemistry perspective. While questioning or revisiting familiar concepts belonging …

Over the last 30 years, geochemical research has demonstrated that abiotic methane (CH4),
formed by chemical reactions which do not directly involve organic matter, occurs on Earth in …

Characteristics of cold seeps at different geologic settings are the subject of this review
primarily based on results of the Research Consortium SFB 574. Criteria are drawn from …

In recent years, methane and other light hydrocarbons with an apparently abiotic origin have
been identified in an increasing number of geologic fluids on Earth. These compounds have …

Abiotic CO2 reduction on transition metal minerals has been proposed to account for the
synthesis of organic compounds in alkaline hydrothermal systems, but this reaction lacks …

Alteration of ultramafic rocks plays a major role in the production of hydrocarbons and
organic compounds via abiotic processes on Earth and beyond and contributes to the …

The fact that mineral deposit attributes such as the size frequency of orogenic gold deposits
in specific provinces exhibit power law distributions similar to forest fires, earthquakes, and …

Carbon can be a major constituent of crustal and mantle fluids, occurring both as dissolved
ionic species (eg, carbonate ions or organic acids) and molecular species (eg, CO2, CO …

Position-specific (PS) carbon isotope compositions of light hydrocarbons such as propane
and butane isomers (n-butane and i-butane) can provide a wealth of information on the …

The compositions of mineral inclusions from a representative collection (more than 140
samples) of diamonds from the placer deposits in the Ural Mountains were studied to …
