摘要：
Interaction of at least two different fluids of different redox state resulted in gold deposition at the Victory-Defiance gold deposit, Yilgarn Craton, Western Australia. The different fluids are associated with different structures. The oxidized fluid was most likely related to felsic or intermediate porphyry intrusions and possibly consisted of CO2-SO2 gas. The reduced fluid was controlled by subvertical WNW-trending structures and locally shallow-dipping thrusts. Fluid interaction was inhibited because of the separation of the fluids along the pathways. Fluid mixing occurred at the depositional site.
