Submarine hydrothermal vents are the only comtemporary geological environment which may be called truly primeval; they continue to be a major source of gases and dissolved elements to the modern ocean as they were to the Archean ocean. Then, as now, they encompassed a multiplicity of physical and chemical gradients as a direct result of interactions between extensive hydrothermal activity in the Earth's crust and the overlying oceanic and atmospheric environments. We have proposed that these… 

A Hydrothermal-Sedimentary Context for the Origin of Life

This work document constant permeation of the porous, carbonaceous, and reactive sedimentary layer by hydrothermal fluids emanating from the crust, representing a widespread system of miniature chemical reactors in which the production and complexification of prebiotic molecules could have led to the origin of life.

Submarine hydrothermal vent systems: the relevance of dynamic systems in chemical evolution and prebiotic chemistry experiments

Since their discovery, submarine hydrothermal vent systems have been pointed out as important places where chemical evolution on Earth could have occurred; and their role in the process has been

Transition metal isotope fractionation in marine hydrothermal deposits of the Mohns Ridge, North Atlantic Ocean

Seafloor hydrothermal vent systems form along mid-ocean ridges in all of the Earth’s oceans. They have a major impact on the chemical exchange between the lithosphere and the hydrosphere, as vast

Bacterial Communities from Deep Hydrothermal Systems: The Southern Gulf of California as an Example of Primeval Environments

Deep hydrothermal systems result from the magmatic and tectonic activity of the ocean floor. This deep extreme biosphere represents a unique oasis of life driven by sulfur-based chemosynthesis

A new symbiotic model for the origin of life at hydrothermal crater-lakes is proposed here, and it is suggested that RNA virus and prions may represent the evolutionary relics of the RNA/protein world that survived as parasites for billions of years.

Can Life Begin on Enceladus? A Perspective from Hydrothermal Chemistry

This paper compares the properties of two proposed sites for the origin of life on Earth—hydrothermal vents on the ocean floor and hydrothermal volcanic fields at the surface—and asks whether similar conditions could have fostered the originof life on Enceladus.

Hydrothermal — From Geology to Technology (Part 1)

The term hydrothermal is of geological origin. A great variety of crystals, minerals, ores and rocks have hydrothermal origin and occur as bulk, fine, ultrafine, and nanosized geologic materials.

Mapping metabolism onto the prebiotic organic chemistry of hydrothermal vents

A unique experimental instrument is developed to systematically explore simulated hydrothermal vent chemistry, focusing on the chemistry of pyruvate, which has both a central role in modern metabolism and was plausibly formed prebiotically at hydroThermal vents.

Organisms of deep sea hydrothermal vents as a source for studying adaptation and evolution

This review describes some current research concerning metabolic and plausible genetic adaptations of organisms in a deep sea environment, usingiftia pachyptila as model.



Hydrothermal processes at seafloor spreading centers

During the past ten years, evidence has developed to indicate that seawater convects through oceanic crust driven by heat derived from creation of lithosphere at the Earth-encircling oceanic

CH4, H2, CO and N2O in submarine hydrothermal vent waters

Hydrothermal circulation systems of mid-ocean ridges profoundly influence the chemistry of the oceans and the oceanic crust1–3. This has been demonstrated for several major and minor constituents of

Initial microbiological response in lakes to the Mt St Helens eruption

No published reports exist on the early stages in the establishment and succession of microbial communities and associated chemical and geochemical transformations in aquatic environments shortly

East Pacific Rise: Hot Springs and Geophysical Experiments

High-resolution determinations of crustal properties along the spreading center were made to gain knowledge of the source of new oceanic crust and marine magnetic anomalies, the nature of the axial magma chamber, and the depth of hydrothermal circulation.

Possible limits on the composition of the Archaean ocean

It has been suggested that the partial pressure of carbon dioxide in the terrestrial atmosphere was larger in the past than it is at present1–4. In particular, partial pressures of 100–1,000 times

Submarine Thermal Springs on the Gal�pagos Rift

It is suggested that two-thirds of the heat lost from new oceanic lithosphere at the Gal�pagos Rift in the first million years may be vented from thermal springs, predominantly along the axial ridge within the rift valley.

An oxygen isotope profile in a section of Cretaceous oceanic crust, Samail Ophiolite, Oman: Evidence for δ18O buffering of the oceans by deep (>5 km) seawater-hydrothermal circulation at mid-ocean ridges

Isotopic analyses of 75 samples from the Samail ophiolite indicate that pervasive subsolidus hydrothermal exchange with seawater occurred throughout the upper 75% of this 8-km-thick oceanic crustal
