Low-molecular-weight hydrocarbons in natural hydrothermal fluids have been attributed to abiogenic production by Fischer-Tropsch type (FTT) reactions, although clear evidence for such a process has been elusive. Here, we present concentration, and stable and radiocarbon isotope, data from hydrocarbons dissolved in hydrogen-rich fluids venting at the ultramafic-hosted Lost City Hydrothermal Field. A distinct “inverse” trend in the stable carbon and hydrogen isotopic composition of C1 to C4… 
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 to
Sources of organic nitrogen at the serpentinite‐hosted Lost City hydrothermal field
The source and cycling of organic nitrogen at an oceanic serpentinizing environment, the Lost City hydrothermal field, is investigated and data indicate nitrogen is readily available to microbial communities at Lost City.
Formation of ethane and propane via abiotic reductive conversion of acetic acid in hydrothermal sediments
It is shown that ethane and propane can be formed by reductive conversion of acetic acid, whose carboxylic group was isotopically equilibrated with the dissolved inorganic carbon pool, revealing a formerly unrecognized formation pathway for two major components in natural gas.
The Production of Methane, Hydrogen, and Organic Compounds in Ultramafic-Hosted Hydrothermal Vents of the Mid-Atlantic Ridge
Abstract Both hydrogen and methane are consistently discharged in large quantities in hydrothermal fluids issued from ultramafic-hosted hydrothermal fields discovered along the Mid-Atlantic Ridge.
Excess methane in continental hydrothermal emissions is abiogenic
Thermogenic hydrocarbons entirely deriving from the thermal degradation of organic matter usually exhibit methane to ethane plus propane ratios smaller than 100. We present hydrocarbon distribution


Hydrocarbons in Hydrothermal Vent Fluids: The Role of Chromium-Bearing Catalysts
Results suggest that the chromium component in ultramafic rocks could be an important factor for FTT synthesis during water-rock interaction in mid-ocean ridge hydrothermal systems, which could help to support microbial communities now recognized in the subsurface at deep-sea vents.
Abiogenic formation of alkanes in the Earth's crust as a minor source for global hydrocarbon reservoirs
The progressive isotopic trends for the series of C1–C4 alkanes indicate that hydrocarbon formation occurs by way of polymerization of methane precursors, and it can now be rule out the presence of a globally significant abiogenic source of hydrocarbons.
A Serpentinite-Hosted Ecosystem: The Lost City Hydrothermal Field
The serpentinite-hosted Lost City hydrothermal field is a remarkable submarine ecosystem in which geological, chemical, and biological processes are intimately interlinked. Reactions between seawater
Low archaeal diversity linked to subseafloor geochemical processes at the Lost City Hydrothermal Field, Mid-Atlantic Ridge.
First analyses of microbial communities inhabiting carbonate chimneys awash in warm, high pH fluids at the LCHF and the predominance of a single group of methane-metabolizing Archaea are reported, expanding the range of known geological settings that support biological activity to include submarine hydrothermal systems that are not dependent upon magmatic heat sources.
Methane- and Sulfur-Metabolizing Microbial Communities Dominate the Lost City Hydrothermal Field Ecosystem
The finding of a diverse microbial ecosystem supported by the interaction of high-temperature, high-pH fluids resulting from serpentinization reactions in the subsurface provides insight into the biogeochemistry of what may be a pervasive process in ultramafic subseafloor environments.
30,000 Years of Hydrothermal Activity at the Lost City Vent Field
The amount of heat produced by serpentinization of peridotite massifs, typical of slow and ultraslow spreading environments, has the potential to drive Lost City–type systems for hundreds of thousands, possibly millions, of years.
Light Hydrocarbon Gases in Guaymas Basin Hydrothermal Fluids: Thermogenic Versus Abiogenic Origin
Light hydrocarbon gases (methane through pentane) in high-temperature hydrothermal fluids of the Guaymas basin, Gulf of California, are predominantly derived from thermocatalysis of organic carbon in
