Fig. 13.1 Distribution of sea-floor hydrothermal vents and related mineral deposits.
Numbers refer to hightemperature hydrothermal vents and related polymetallic sulfide deposits (closed circles).
Other hydrothermal
deposits and low-temperature vent sites, including Fe-Mn crusts and metalliferous sediments, are indicated by open
circles (from Hannington et al., 2005). Major spreading ridges and subduction zones are indicated.
