The Yangla copper deposit, situated in the middle section of Jinshajiang tectonic belt between Zhongza-Zhongdian plate and Changdu-Simao plate, is a representative and giant copper deposit that has been discovered in Jinshajiang-Lancangjiang-Nujiang region in recent years. Metalliferous minerals consist of chalcopyrite, pyrite, pyrrhotite, galena, bismuth, bismuthinite, arsenopyrite, cobaltite and molybdenite. Based on the mineral association, the paper infers that the deposit is a medium to high temperature hydrothermal deposit. There is a coupled relationship between Yangla granodiorite and copper mineralization in the Yangla copper deposit. A comparison of the REE and trace element compositions of the copper ores with those of the Yangla granodiorite, and S, Pb isotopic composition of the Yangla copper deposit indicate that the ore-forming fluids are derived mainly from the mantle, with minor contributions from the magma.
