Orogenic gold deposits are the most important sources of gold. Fundamental questions regarding their fluid source and gold precipitation process, however, remains. This work addresses some of these questions through the multi-disciplinary investigation of the Kanowna Belle gold deposit in the Yilgarn Craton (Western Australia). Geological observation and geochronology demonstrated that the Kanowna Belle Deposit is a polyphased deposit with mineralisation events separated by 30 million years. Multiple sulfur isotopes established that the Au mineralisation mainly derived from a mantle source and later precipitated through fault-valve process. Formation of different forms of gold in pyrite is controlled by micro-scale processes.
