Partial Chemical Equilibrium

  • Naotatsu Shikazono


It is indicated that the partial chemica l equilibrium model can explain hydrothermal alteration of basalt (e.g. seawater -basalt reaction ). The effects of separation of vapor phase and liquid phase and boiling are considered. It is also indicated that the mixing of fluids results to the precipitation of minerals and formation of hydrothermal ore deposits (e.g. Kuroko-type deposits, mid-oceanic ore deposits, gold deposits).
