| 摘 要： | 根据化学组成、稀土元素、微量元素等特征对白锡腊矿区岩浆岩进行了系统研究。结果表明：该区岩浆岩是由来自深部的碱性－超碱性玄武岩浆分异结晶而成，晚期向富碱、富硅演化，形成了与富铜矿化关系密切的基性脉岩。

| Abstract: | Systematical studies of the magmatic rocks in the Baixila mining area have undergone on the basis of the chemical composition,REE trace element etc,which indicate that the magmatic rocks in the area were formed by fraction and crystallization of the alkalic-ultra alkalic basalt magma from the same depth,and trended to form the basic dike rocks closely related to the high grade copper mineralization as their evolution to the enrichment of alkali and silica at the late stage. |
