Submarine hydrothermal vents are geochemically reactive habitats that harbour rich
microbial communities. There are striking parallels between the chemistry of the H2–CO2 …

Here, we review the relationship between the distribution of modern-day seafloor
hydrothermal activity along the global mid-ocean ridge crest and the nature of the mineral …

In recent years, serpentinized ultramafic rocks have received considerable attention as a
source of H2 for hydrogen-based microbial communities and as a potential environment for …

Serpentinites are an important component of the oceanic crust generated in slow to
ultraslow spreading settings. In this context, the MOHO likely corresponds to a hydration …

Abyssal peridotite from the 15° 20′ N area of the Mid-Atlantic Ridge show complex
geochemical variations among the different sites drilled during ODP Leg 209. Major element …

Abstract The ultraslow-spreading Southwest Indian Ridge is a major tectonic province,
representing one of the important end-member mid-ocean-ridge types for its very slow and …

A high-resolution mapping and sampling study of the Gakkel ridge was accomplished during
an international ice-breaker expedition to the high Arctic and North Pole in summer 2001 …

The results of detailed textural, mineral chemical, and petrophysical studies shed new light
on the poorly constrained fluid‐rock reaction pathways during retrograde serpentinization at …

Hydrothermal venting and the formation of carbonate chimneys in the Lost City hydrothermal
field (LCHF) are driven predominantly by serpentinization reactions and cooling of mantle …

We present first results of a petrographic study of hydrothermally altered peridotites drilled
during Ocean Drilling Program (ODP) Leg 209 in the 15° 20′ N fracture Zone area on the …
