伟晶岩伟晶岩pegmatite一种颗粒粗大的脉状火成岩。常呈脉状体成群出现。具巨晶粗粒结构，带状构造。按矿物组合，可分为花岗伟晶岩、霞石正长伟晶岩、辉长伟晶岩等，但以花岗伟晶岩分布最广。花岗伟晶岩的化学成分和矿物成分与花岗岩相似，主要由钾长石、石英和云母等的粗大晶体所组成，但较花岗岩更富含稀有元素矿物，如锂云母、绿柱石、铌钽铁矿、锆石等。通常分为简单伟晶岩和复杂伟晶岩两种类型。前者矿物成分简单，主要由长石、石英组成，分带不明显，稀有元素矿物数量较少；后者的矿物成分复杂，富含稀有元素和挥发分矿物，分带现象明显。一般情况下，从边部到核心伟晶岩脉可分为4个带：①边缘带。主要由细粒石英、长石组成。副矿物种类较少。②外侧带。位于边缘带的内侧，矿物颗粒较粗大，出现绿柱石等稀有元素矿物。③中间带。位于外侧带和内核带之间，带的厚度既宽又稳定，矿物成分、种类复杂多样，颗粒粗大。④内核带。位于伟晶岩脉的核心，主要为石英，亦称石英核。与之有关的矿产有水晶、长石、白云母以及其他锂、铍、铌、钽等稀有元素矿床和宝石矿床。文象伟晶岩标本
