| 摘 要： | 108沟铜矿位于西南三江有色、责金属成矿带中段乡城茶拥当卓-稻城铅锌银铜区成矿带北部。铜矿体呈脉状赋存于马熊沟一次林措复式花岗岩带旁侧的三叠系上统拉纳山组变质砂板岩中，受断层破碎带、层间破碎带控制。矿化以热液充填为主，围岩蚀变主要有硅化，次为绢云母化、绿泥石化、碳酸盐化和黄铁矿化，富集程度与硅化成正比。矿床成因属与花岗岩有关的中低温热液型铜矿。

| Abstract: | 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. |
