| 摘 要： | 舍索铜多金属矿床位于西藏申扎县雄梅乡政府所在地南4km处。为现今在冈底斯北麓正在开采的少数矽卡岩型铜矿床之一。由辉钼矿测年结果可以看出，Re-Os等时线为116.2±1.9 Ma，而模式年龄的平均值为115.7±1.3 Ma。因此，舍索矿床的成矿年龄应为116 Ma，为燕山晚期的产物。其成矿年龄与冈底斯成矿带的相距较远，而与班公湖-怒江成矿带的相近，为班公湖-怒江缝合带闭合之后碰撞后阶段的产物，其成矿物源与壳源关系更为密切。

| Abstract: | Shesuo copper polymetallic ore deposit is located in 4km of south of Xiongmei town, Shenzha county, Tibet. It is one of several deposits, located in the north part of Gangdese ore belt, that is exploring at present .The age of Re-Os isotime line from molybdenite is 116.2±1.9 Ma. The average age of model is 115.7±1.3 Ma.Therefore the age of Shesuo copper polymetallic ore deposit is 116 Ma.It is the late of Yanshan epoch . It is obviously different with that of Gangdesi ore belt,but near that of Bangong Co-Nujiang belt.So this deposit is the result of postcollision of Bangong Co-Nujiang belt.Ore-forming material of it is closely related to the crust. |
