摘要
甲基卡稀有金属花岗伟晶岩矿床以锂为主,伴生有铍、铌钽矿。伟晶岩脉主要产于甲基卡二云母花岗岩的周围,受花岗岩体的控制。矿脉按主要矿物含量及共生组合关系分为五种类型,各类型的伟晶岩脉沿二云母花岗岩体呈水平分带。研究伟晶岩脉的产出特征对今后的类似的稀有金属矿床的找矿工作具一定的找导意义。
The Jiajika rare-metal granitic pegmatite deposit is a Li deposit associated with Be, Nb and Ta. Ore-bearing pegmatite dykes occur round the Jiajika binary granite rock mass and are controlled by the rock mass. The dykes may be divided into 5 types based on ore-forming elements and is characterized by horizontal zoning.
