Abstract: Ailaoshan metallogenic belt is the most advantaged gold belt in Southwest China. The gold metallogenesis is closely related to fault structure and magma activity of Himalaya epoch. The spatial distribution of ore belt and position of ore bodies are strictly controlled by structures. Based on the analysis of regional metallogenic characteristics and orecontrolling factors, with all kinds of synthesized information about metallogenic prospecting, four gold prospective areas (A1, A2, B1 and B2) are delineated. The prospecting types, criteria and targets are also pointed out.
