Abstract：The “Sanjiang metallogenic belt” in southwestern China is tectonically located in the convergence zone between the Indian plate and Yangtze plate. In recent years, breakthroughs have been made successfully in copper, gold and lead-zinc (silver) exploration in the south-central segment of the belt where magmatism was strong, metamorphism was extensive and mineralization types were highly varied. Based on geological, geophysical and geochemical studies of major large and medium-sized mineral deposits in the metallogenic belt in Yunnan, China, the paper discusses the integrated information ore-finding model and indicators and presents new ore-finding ideas and direction in terms of time and space.
