1区域成矿背景木里县地处青藏高原南缘横断山脉中段,德工牛场铜矿位于甘孜-理塘断裂带中南段。众所周知,甘孜-理塘断裂带是三江成矿带东缘重要的Au、Cu多金属成矿带,是发育在印支期的板块结合带以及甘孜-理塘洋脊型火山岩-蛇绿岩带之上的成矿断裂带;北段为张性弧,有大量的火山喷发,形成大型块状硫化物矿床。南段是压性弧,发育大量中酸性斑岩,具有形成斑岩铜矿
1 Regional Metallogenes Background Muli County is located in the middle of the Hengduan Mountains on the southern margin of the Qinghai-Tibet Plateau. The Degan Niuchang Copper Mine is located in the central-southern part of the Garze-Litang Fault Zone. It is well-known that the Ganzi-Litang fault zone is an important Au, Cu polymetallic metallogenic belt at the eastern margin of the Sanjiang metallogenic belt and is a member of the Indosinian plate assemblage and the Ganzi-Litang ridge-type volcanic-ophiolite belt Above the metallogenic fault zone; the northern section of Zhang arc, a large number of volcanic eruptions, the formation of large massive sulfide deposits. The southern section is a compressive arc, developing a large number of acidic porphyry, with the formation of porphyry copper deposit
