Carlin-type systems occur in continental magmatic arcs, but are remote from subjacent stocks and plutons. Consequently, ore fluids consist largely of meteoric water containing volatiles discharged from deep intrusions. Ore fluids scavenge elements from carbonaceous pyritic sedimentary rocks as it convects through them. Gold ore containing disseminated pyrite forms where acidic reduced fluids dissolve carbonate and sulfidize Fe-bearing minerals in host rocks. As, Hg, and Tl minerals precipitate by cooling. Stibnite precipitates with quartz by cooling from Au, As, Hg, Tl depleted fluids.
