Analysis on Metallogenic Structural of Porphyry Cu-Mo-Au Deposit of Baoxingchang,Yunnan Province

Baoxingchang porphyry copper-molybdenum-gold deposit is located in the ore district of Lijiang-Dali area,this is a porphyry deposit of more comprehensive of metallogenic series,complex ore-forming elements and unique metallogenic conditions.The geological conditions of ore area is complex,structure and magmatic activity are frequent,NW trending Jinshajiang-Ailaoshan fault zone and NNE trending Chenghai-Binchuan fault zone form structural deformation area of triangle,it become a channel of through the bottom of lithosphere,Himalayan regional strike-slip orogenic activity lead to the intrusive of mantle-crustal alkali-rich porphyry,the mineralization is closely related to alkali-rich porphyry of Machangqing.The series of antiform and syncline are ore controlling structure,such as Jinchangqing-Rentouqing,Luantongshan-Baoxingchang and so on.Machangqing alkali-rich porphyry and its contacts with wall-rock are favorable positions of Cu-Mo-Au mineralization.
