摘　　要：京西红柱石是典型的接触变质条件下形成的矿化区，控矿条件主要有：一是铝饱和程度高的沉积岩，二是燕山期岩体侵入所产生的热变质作用。该地区红柱石矿床工业可利用性评价，曾一度认为红柱石选别性不好而中断了地质工作。经过本次研究和试验，重新肯定了工业利用价值。红柱石含量居我国大型矿床之首，矿石量在１亿吨以上，矿物量大于２０００万吨，并具有开采条件好，交通便利等优越条件，是一个理想的红柱石原料生产基地。The andalusite deposit in the west of Beijing is of typical contact metamorphic ore deposit.The main ore-controling factors are the sedimentary rocks with high degree of Al saturation and heat metamorphism derived from intrussive body of Yanshanian Period. Geological work was stoped by the former ore-dressing test which showed problems in andalusite beneficiation. It is a large size deposit with ore reserve of 100 million ton and andalusite mineral reserve of 200 million ton. This paper represents the results of the latest research and test carried out by the authors reproving its industrial value. It isaideal mining base with convnient transportation and communication.
