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 and upper mantle peridotite produce methane- and hydrogen-rich fluids, with temperatures ranging from <40° to 90°C at pH 9 to 11, and carbonate chimneys 30 to 60 meters tall. A low diversity of microorganisms related to methane-cycling Archaea thrive in the warm porous interiors of the edifices… Expand
Microbial utilization of abiogenic carbon and hydrogen in a serpentinite-hosted system
Abstract Mantle rocks exposed on the seafloor constitute a highly reactive chemical and thermal system, in which interaction with seawater to produce serpentinite has major consequences forExpand
Sources of organic nitrogen at the serpentinite-hosted Lost City hydrothermal field.
TLDR
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. Expand
Evidence for archaeal methanogenesis within veins at the onshore serpentinite-hosted Chimaera seeps, Turkey
Abstract Serpentinite-hosted ecosystems are potential sites where life may first have evolved on Earth. Serpentinization reactions produce strongly reducing and highly alkaline fluids that areExpand
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.

Fossil evidence for serpentinization fluids fueling chemosynthetic assemblages
TLDR
This finding shows that serpentinization-related fluids, unaffected by high-temperature hydrothermal circulation, can occur on-axis and are able to sustain high-biomass communities. Expand
Hydrothermal vents and the origin of life
Submarine hydrothermal vents are geochemically reactive habitats that harbour rich microbial communities. There are striking parallels between the chemistry of the H2–CO2 redox couple that is presentExpand
Serpentinization and carbon sequestration: A study of two ancient peridotite-hosted hydrothermal systems
Fluid circulation in peridotite-hosted hydrothermal systems influences the incorporation of carbon into the oceanic crust and its long-term storage. At low to moderate temperatures, serpentinizationExpand
Microbial ecology of the newly discovered serpentinite-hosted Old City hydrothermal field (southwest Indian ridge)
TLDR
The microbial ecology of the ‘Lost City’-type Old City hydrothermal field, recently discovered along the southwest Indian ridge, is presented and this first description of its microbial ecology opens up attractive perspectives for understanding environmental factors shaping communities and metabolisms in oceanic serpentinite-hosted ecosystems.

Fluid mixing and the deep biosphere of a fossil Lost City-type hydrothermal system at the Iberia Margin
TLDR
Examination of fossil microbial communities and fluid mixing processes in the subseafloor of a Cretaceous Lost City-type hydrothermal system at the magma-poor passive Iberia Margin appears that, wherever they occur, they can support microbial life, even in deep subseAFloor environments. Expand
A serpentinite-hosted ecosystem in the Southern Mariana Forearc
TLDR
The SSF appears to be a serpentinite-hosted ecosystem within a forearc (convergent margin) setting that is supported by fault-controlled fluid pathways connected to the decollement of the subducting slab, and supports the prediction that serpentinization of peridotite vents may be widespread on the ocean floor.

Low archaeal diversity linked to subseafloor geochemical processes at the Lost City Hydrothermal Field, Mid-Atlantic Ridge.
TLDR
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.
