The Valley 108 Cu deposit in Xiangcheng, Sichuan lies in the north of Chayongdangzhuo-Daocheng Pb-Zn-Ag-Cu ore zone in the middle sector of the Sanjiang metallogenic belt. Cu orebodies occur as lodes in metamorphosed sandy slate of the Upper Triassic Lanashan Formation close by the Maxionggou-Cilincuo granite intrusion and are controlled by fault and interlayer fractural zone with wallrock alteration silisification, sericitization, chloritization, carbonation and pyritization. Hydrothermal filling mineralization has a direct relationship to silisification. The deposit belongs to mesothermal and epithermal one.
