The majority of life on Earth—notably, microbial life—occurs in places that do not receive
sunlight, with the habitats of the oceans being the largest of these reservoirs. Sunlight …

Until 1985, seven vent fields were described from the Mid-Atlantic Ridge (MAR). An eighth
field, Mount Saldanha (36° N), discovered in 1998, showed unusual geological and …

The Flores diving cruise was part of the MAST III-AMORES (1995–1998) program funded by
the European Union. One of the major achievements of the Flores cruise was the discovery …

Fluids were collected from the Rainbow vent field (36° 14′ N) on the Mid-Atlantic Ridge
(MAR) during the 1997 diving FLORES cruise. This vent field, in ultramafic rocks at a depth …

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 …

The" magmatic budget hypothesis" proposes that variability in magma supply is the primary
control on the large-scale hydrothermal distribution pattern along oceanic spreading ridges …

Olivine (Fo89), orthopyroxene (En85), and clinopyroxene (Di89) were reacted, individually
and in combinations, with NaCl-MgCl2 at 400° C, 500 bars to better assess alteration and …

The Lost City Hydrothermal Field at 30° N, near the Mid-Atlantic Ridge, is an off-axis,
moderate temperature, high-pH (9–10.8), serpentinite-hosted vent system. The field is …

The first building blocks of life could be produced in ultramafic-hosted hydrothermal systems
considering the large amounts of hydrogen and methane generated by serpentinisation and …
