Seafloor massive sulfide (SMS) deposits form in a suite of hydrothermal settings across a
range of depths. Many deposits are of a tonnage and mineral grade comparable to land …

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 …

Rare earth element (REE) and yttrium (Y) concentrations were measured in fluids collected
from deep-sea hydrothermal systems including the Mid-Atlantic Ridge (MAR), ie, Menez …

Seafloor hydrothermal activity at mid-ocean ridges has a major impact on the chemistry of
the oceans [Edmond et al., 1979] and has been responsible for extensive alteration of …

Hydrothermal vent communities from 76 areas lying at depths from 0 to 4100 m were split
into two groups—“deep” and “shallow-water”, based on the occurrence of vent obligate …

During the DIVA 1 cruise in May 1994, a series of 19 dives was conducted using the French
submersible Nautile at the topographic highs of three volcanic segments centered at 37° …

At Lucky Strike near the Azores Triple Junction, the seafloor setting of the hydrothermal field
in a caldera system with abundant low-permeability layers of cemented breccia, provides a …

The Lucky Strike hydrothermal field occurs in the summit basin of a large seamount that
forms the shallow center of a 65 km long ridge segment near 37° N on the Mid-Atlantic …

In this paper, we present the copper isotope signatures of black smoker sulfides, massive
sulfides, and their alteration products and provide new insights into mineralization …
