A thermodynamic explanation for black smoker temperatures

Article Abstract:

The internal temperature structure of convection cells in a porous medium was examined. It was shown that plumes of pure water form naturally at pressures appropriate to seafloor crust. Higher temperatures were confined to a boundary layer where flow is horizontal. The model predicts that high-temperature reaction zones occur in ophiolites.

Earthquake-induced changes in a hydrothermal system on the Juan de Fuca mid-ocean ridge

Article Abstract:

Research is presented concerning the temperature changes which occurred in the hydrothermal vents of the Juan de Fuca ridge before, during and after an earthquake which was tectonic in origin.
