As a typical porphyry Cu-Mo-Au ore concentration area related to alkaline-rich intrusive rocks in western Yunnan ore belt, Machangqing has many mineralization types such as porphyry Cu-Mo mineralization, contact metasomatic Cu-Mo-Au mineralization and hydrothermal Au-Ag-Pb-Zn lodes. Based on a detailed analysis of the mineralization evidence and the structure of the ore system, the authors concluded that the thermal dynamic force from Machangqing intrusion caused the migration of the ore-forming fluid from the magma outwards. With the variation of physical and chemical conditions of fissures in the intrusive body as well as contact structures and fracture zones in the wall rock, there occurred different mineralization types and metallogenic element associations under different conditions.
