| Abstract: | The orefield is in the transitional part from Yangzi Paraolafform to Sanjiang Fold Belt in belonging to the S part of Lijiang platform margin fold belt, and in the and Jinshajiang-Ailaoshan megafault. The main outcropping strata in limestone, porphyry, Kanglang monzonite reverse delta triangle area between this area are Lower D Qingshan tectonics, Chenghai Formation Formation dolomitic limestone, Lower 0 quartz sandstone and the magmatic rocks are granite porphyry, lamprophyre and diabase. The metallogeneisis type can be divided into 4 kinds, ie, red clay, sedentary-slope wash, structure fracture zone |
