Porphyry ore deposits are the source of much of the copper, molybdenum, gold and silver
used by humans. Porphyry ore typically forms in magmatic arcs above subduction zones …

Current models of the formation and distribution of gold deposits on Earth are based on the
long-standing paradigm that hydrogen sulfide and chloride are the ligands responsible for …

Gold is either the only economically important metal or a major by-product in 11 well-
characterized deposit types—paleoplacer, orogenic, porphyry, epithermal, Carlin, placer …

We determined the concentrations of gold, silver, arsenic, antimony, and mercury in deep
