2.7 Orogenic mineral system | Geoscience Australia

One of the unifying characteristics of lode gold deposits through time and space are low- to moderate-salinity (generally <10 eq wt % NaCl), CO 2-bearing ore fluids (Ridley and Diamond, 2000). The origin of these fluids is contentious, with some workers inferring a metamorphic origin (Phillips, 1993), but others prefering a magmatic-hydrothermal origin, at least in part (Mueller et al., 1991).
