... in the least fractionated low-salinity fluids. This, together with other lines of evidence, suggests that brine condensates play a central role in the formation of Sn, W, Mo, and REE deposits. In the case of porphyry Cu (-Au) systems it appears more likely that the greater proportion of metal precipitated from...
