The physical and tectonic setting of highsulfidation epithermal deposits is distinct from lowsulfidation epithermal deposits such as El Peñón (Chile), Fruta del Norte (Ecuador) or those of Patagonia. The latter range to significantly older ages (Jurassic to early Eocene), occur at lower elevations and were emplaced in extensional settings.
