摘要
The western Yunnan area, an important part of the Sanjiang composite orogenic belt in the southwestern part of China, is located in the special position between the Yangtze plate and the India plate. Geological data revealed a complex structure in this area. Composite analysis indicated that the special structural position and the regional evolution history of dynamic transition of the western Yunnan area in Late Yanshanian to Himalayan epochs should be responsible for the formation of the structures in the crust and mantle. They were also should be a triggering to the extensive crust-mantle interaction. The upwelling pulses of lithosphere mantle would be the fundamental control to the multi-stage mineralization events.
