Iron oxide copper gold deposits (IOCG) are a globally important source for Cu, Fe and Au, but also for strategic elements such as Co, U and REE. Despite their relevance these deposits comprise an ill-defined clan with a broad range of different genetic models that impact proper exploration. Within this scenario geochemical proxies have proven to be a more successful tool for characterizing IOCG deposits, focusing on pyrite, magnetite and more recently actinolite. The chemical and isotopical variations of these minerals provide unique information on the hydrothermal fluid composition, source and temperature variations. The results that will be shown suggest that IOCG deposits form through a complex story of episodic pulsing, focusing and cooling of hydrothermal fluids.
