Being located in the eastern edge of the Tibetan plateau,the geological structure of western Sichuan presents significant complexity and diversity because of the interaction of the India plate,the Pacific plate and the Eurasian plate. Its unique evolutionary process and intense both structure and magma activity create favorable and special metallogenic geological environment,making it an important metal metallogenic area. Porphyry copper polymetallic deposits in Yidun island arc relating to acidic shallow-ultra shallow intrusive magmatic activity concentrate in the southern section of main island arc zone-Xianggelila tectonic magmatic zone which mainly produced in Indosinian and acted approximately in 208235Ma. There are Pulang large porphyry copper and Xuejiping medium porphyry copper. No porphyry copper was found before the 1970s in the northern Yidun island arc until Changdagou porphyry copper deposits which is large-scale and high-grade has been researched.
