伟晶岩矿床

如同伟晶岩矿床的成矿流体具有残余熔浆特征一样，石英脉型W、Sn矿床的成矿流体也可能具有熔浆&热液过渡性质。

The larger F - / C1 - ratio may drop a hint that the ore-forming fluids of the pegmatite deposits and the quartz-vein type of W-Sn deposits are magma-hydrothermal solution fluid of intermediate property .

国内外伟晶岩及伟晶岩矿床的研究比较薄弱，对于伟晶岩矿床在造山过程中的示踪更是知之甚少。

Compared with deposits genetically related to granites or basalts , the study of pegmatite and its related deposits is very defective .

因此，丹巴白云母矿化伟晶岩脉是地壳活动相对宁静期的产物，与世界上一些重要伟晶岩型矿床的成矿规律一致。

Thus , the pegmatite type muscovite deposit must have been formed in a stable period of crustal movement , and hence its metallogenic regularity is consistent with that of some important pegmatite type deposits in the world .

伟晶岩脉及其矿体的分布受北北东北东向和北西向断裂控制，北北东北东向分布的伟晶岩矿床以稀有金属矿种为主，北西向分布的伟晶岩矿床以稀土金属矿种为主。

The distribution of pegmatite veins and their orebodies are controlled by the fractures of NNE to NE strike and NE strike .
