The effect of volcanic activity on submarine hydrothermal systems has been well documented along fast‐ and intermediate‐spreading centers but not from slow‐spreading ridges. Indeed, volcanic eruptions are expected to be rare on slow‐spreading axes. Here we report the presence of hydrothermal venting associated with extremely fresh lava flows at an elevated, apparently magmatically robust segment center on the slow‐spreading southern Mid‐Atlantic Ridge near 5°S. Three high‐temperature vent… 
Hydrothermal plume mapping as a prospecting tool for seafloor sulfide deposits: a case study at the Zouyu-1 and Zouyu-2 hydrothermal fields in the southern Mid-Atlantic Ridge
Seafloor hydrothermal polymetallic sulfide deposits are a new type of resource, with great potential economic value and good prospect development. This paper discusses turbidity, oxidation–reduction
Hydrothermal nontronite formation associated with microbes from low‐temperature diffuse hydrothermal vents at the South Mid‐Atlantic Ridge
Oceanic nontronite deposits have been identified to be closely related to low‐temperature hydrothermal activities. However, their formation mechanisms associated with microbes in diffuse hydrothermal

Evolution of East Pacific Rise hydrothermal vent fluids following a volcanic eruption
STUDIES of sea-floor hydrothermal vent fluids have shown them to have stable characteristics on a decade timescale1, with temperatures in the range 350 ± 30 °C (ref. 2) and chemistries2 that vary
Magmatic events can produce rapid changes in hydrothermal vent chemistry
TLDR
Volatile data from this event and an earlier one at 9° N on the East Pacific Rise show that such magmatic events can have profound and rapid effects on fluid–mineral equilibria, phase separation, 3He/heat ratios and fluxes of volatiles from submarine hydrothermal systems.
Chemistry of hydrothermal vent fluids from 9°–10°N, East Pacific Rise: “Time zero,” the immediate posteruptive period
In 1991, vent fluids were sampled from 10 high temperature hydrothermal vent sites within weeks of a volcanic eruption/dike intrusion on the East Pacific Rise, between 9° and 10° north latitude, and

TLDR
Chemical data for CoAxial vents presented here are consistent with this evolution of phase separation and enhanced volatile fluxes associated with volcanic eruptions, with vapour–dominated fluids predominating in the initial post–eruption period, followed in time by brine-dominated fluids, consistent with temporary storage of brine below the seafloor.
Discovery of a magma chamber and faults beneath a Mid-Atlantic Ridge hydrothermal field
TLDR
It is suggested that this magma chamber beneath the slow-spreading Lucky Strike segment of the Mid-Atlantic Ridge provides the heat for the active hydrothermal vent field above it, and axial valley bounding faults that seem to penetrate down to the magMA chamber depth are observed, suggesting continuous interactions between tectonic and magmatic processes.
On the Global Distribution of Hydrothermal Vent Fields
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. The concept is
