| 摘 要： | 辽宁后仙峪硼矿区 ,含矿层蚀变广泛而强烈 ,且具明显的分带性。其中金云母岩多分布在含矿层外带 ,通过对 1 8件金云母岩样品中B2 O3含量分析 ,表明正常蚀变岩中的金云母岩与硼矿有一定的关系 ,而由闪长玢岩脉体侵入影响下形成的金云母岩则与矿化无关。以此规律指导找矿 ,已取得了良好的效果

| Abstract: | The ore beds of the Houxianyu boron deposit in Liaoning province is widely altered with prominent alteration zonation. According to petrologic analysis of 18 samples of altered rock, phlogopite rock, with regard to its B 2O 3 content, it is generally restricted to the outside of the ore bed, having certain ties with the boron minerlization while no ties are found in altered rock of the same type associated with veins of diorite porphyrite. Taking this regularity as guide to ore hunting has yielded better results in searching for boron occurrences in the study area. |
