Our distinction of fluid end members based on trace elements is supported by data reported from other hydrothermal ore deposits. Fluid inclusion analyses from Bingham Canyon and other porphyry Cu-Mo-Au deposits confirm selective enrichment of B and As in magmatic vapor, in contrast to enrichment of Rb, Cs, and K in magmatic brines ( Fig. 3 ...
