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 .

丹巴伟晶岩脉的形成与区域地壳活动构成构造→岩浆→变质→伟晶岩脉的旋回，形成于喜马拉雅运动开始之前。

The pegmatite dikes and regional crustal movement constitute a circle of tectonic activity → magmatism → metamorphism → pegmatite formation , and the pegmatite dikes were formed before the Himalayan movement .

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 .
