This two-day course will bring together a group of international experts to review current understanding of the geology and exploration characteristics of IOCG deposits, with emphases on metallogenesis and examples of world-class districts in different tectonic environments. Commonalities among the studied IOCG systems in terms of alteration zoning, mineralization styles, geochemical footprints, fluid regimes and ore deposition processes will be highlighted to frame the wide range of IOCG deposits into a conceptual evolutionary magnetite-group to hematite-group IOCG deposit model. The potent mineralizing effects of mixing of fluids from different sources in geodynamic environments that can sustain thermal crustal anomalies will be addressed to explain how series of world-class deposits can cluster within a single district. Finally, now that analytical breakthroughs are providing a better constraint on IOCG’s fluid sources and reconciling debates over the ‘right’ metallogenic model, it is time to ponder on the role of magmatism in the genesis of some components of low-Ti magnetite-apatite deposits and the role of geology in increasing effectiveness of exploration for IOCG deposits from under cover to well exposed settings.
