Gold concentrations of magmatic brines and the metal budget of porphyry copper deposits

Porphyry copper–molybdenum–gold deposits are the most important metal resources formed by hydrothermal processes associated with magmatism. It remains controversial, however, whether the metal content of porphyry-style and other magmatic–hydrothermal deposits is dominantly controlled by metal partitioning between magma and an exsolving magmatic fluid phase… CONTINUE READING
