| 摘 要： | 辽东硼矿床赋存于辽东古元古代的镁质火山-沉积地层中.矿石与含矿岩系具密切的交代继承关系：（1）矿石与含矿镁质岩石具交代继承的矿物组成、结构构造；（2）矿石的稀土元素特征主要受含矿岩系岩石的控制，在混合岩化弱的含矿岩系中，矿石的稀土元素特征与含矿镁质岩石相似，而在混合岩化强的含矿岩系中的矿石与混合岩的稀土元素特征相近；（3）辽东的硼矿床的形成是在混合岩作用过程中形成的含硼成矿流体交代镁质岩石的结果.

| Abstract: | The boron deposits in eastern Liaoning Province occur in the Paleoproterozoic magnesian volcanic-sedimentary strata. The rocks have undergone regional metamorphism and migmatization. The REE characteristics of ores are controlled by the boron-bearing rocks and migmatization, indicating that the ore-forming fluids formed in the regional metamorphism and migmatization play an important role in the formation of the borate deposits. The formation of the borate deposits in Eastern Liaoning is the result that the boron-bearing fiuids replace the magnesian rocks. |
