In hydrothermal circulation systems, cold seawater seeps into permeable ocean crust and reacts with subsurface rocks.
The implications of this find, saysRona, "are that slow-spreading ridges may be more effective at concentrating larger sulfide deposits than are fast-spreading ridges, where the crust moves away much sooner from the heat source driving hydrothermal circulation.
