    Orogenic gold deposits are a widespread coherent group of epigenetic ore deposits that are sited in accretionary or collisional orogens. They formed over a large crustal-depth range from deep-seated low-salinity H2O-CO2 CH4 N2 ore fluids and with Au transported as thio-complexes. Regional structures provide the main control on deposit distribution.
