Natural hydrocarbons are largely formed by the thermal decomposition of organic matter (thermogenesis) or by microbial processes (bacteriogenesis). But the discovery of methane at an East Pacific Rise hydrothermal vent and in other crustal fluids supports the occurrence of an abiogenic source of hydrocarbons. These abiogenic hydrocarbons are generally formed by the reduction of carbon dioxide, a process which is thought to occur during magma cooling and—more commonly—in hydrothermal systems… Expand
Unravelling abiogenic and biogenic sources of methane in the Earth's deep subsurface
At four underground sites in Precambrian Shield rocks in Canada and South Africa, hydrocarbon and hydrogen gases exsolving from saline fracture waters are analyzed for compositional and isotopicExpand
Abiotic Hydrocarbons Discharge from A Felsic Rock-Hosted Hydrothermal System
Abiogenic hydrocarbons are fundamentally important for understanding the deep microbial communities and the origin of life. The generation of abiogenic hydrocarbons was proposed to be limited toExpand
Isotopic signatures of CH4 and higher hydrocarbon gases from Precambrian Shield sites: A model for abiogenic polymerization of hydrocarbons
Abstract Previous studies of methane and higher hydrocarbon gases in Precambrian Shield rocks in Canada and the Witwatersrand Basin of South Africa identified two major gas types. PaleometeoricExpand
Using Carbon, Hydrogen and Helium Isotopes to Unravel the Origin of Hydrocarbons in the Wujiaweizi Area of the Songliao Basin, China
Although abiogenic hydrocarbons have been found in deep-sourced geofluids, they have not been considered a significant source for global hydrocarbon reservoirs. Here, we report a multi-isotopic (C, HExpand
Natural evidence for rapid abiogenic hydrothermal generation of CH4
Abstract Although recent hydrothermal experiments imply that abiogenic methane (CH 4 ) generation from hydrothermal reduction of CO 2 can occur, evidence from natural systems was still lacking. BasedExpand
Abiogenic Hydrocarbon Production at Lost City Hydrothermal Field
TLDR
Concentration, and stable and radiocarbon isotope, data from hydrocarbons dissolved in hydrogen-rich fluids venting at the ultramafic-hosted Lost City Hydrothermal Field show a distinct “inverse” trend in the stable carbon and hydrogen isotopic composition of C1 to C4 hydrocars, compatible with FTT genesis.

Abiogenic hydrocarbon isotopic signatures in granitic rocks: Identifying pathways of formation
Abstract The stability and isotopic composition of hydrocarbons formed in the mantle are controversial subjects. Knowing the range in isotopic compositions of abiogenically-derived hydrocarbons isExpand

Abiogenic methane formation and isotopic fractionation under hydrothermal conditions
TLDR
Isotopic fractionation by the catalyst resulted in delta(13)C values of the CH(4) formed that are as low as those typically observed for microbial methane, which suggests that abiogenic methane may be more widespread than previously thought. Expand

Abiogenic methanogenesis in crystalline rocks
Isotopically anomalous CH4-rich gas deposits are found in mining sites on both the Canadian and Fennoscandian shields. With δ 13CCH4 values from −22.4 to −48.5% and δDCH4 values from −133 to −372%,Expand
Carbon isotope composition of low molecular weight hydrocarbons and monocarboxylic acids from Murchison meteorite
TLDR
The results suggest the possibility that the production mechanisms for hydrocarbons and carboxylic acids may be similar and impose constraints on the identity of the reactant species, and are consistent with the kinetically controlled synthesis of higher homologues from lower ones. Expand
