2011-7-1 The salinity and temperature of ore-forming fluids have wide ranges. Salinities of some ore-forming fluids are lower than sea water, whereas those in fluids forming porphyry deposits can reach 80 wt.% NaCl (Heinrich, 2007).The salinity and temperature of most hydrothermal fluid decrease during the late-stages of ore formation, suggesting either the attenuation of heat and fluid source or the
