| 摘 要： | 毕家山多金属矿床关键性地质问题的研究结果表明,本区铅锌矿具有显著的层控特征,它们常产于某些特定的地层层位,与一定的岩性组合和沉积类型有关.但具工业意义的矿体产出受东西向和北东东向构造控制,北东东向构造为富矿的主导控矿构造.较大而富的矿体往往赋存于受北东东向断裂活动而形成牵褶曲核部以及层间滑移带中,而最有利的成矿部位则是两种构造成分相复合的部位.

| Abstract: | Based on the research of key geology problems of Bijiashan polymetallic deposit, it is found lead-zinc ores in this area possesses notable stratabound characters, are distributed in some specific stratum layer, and are related with certain rock combination and sedimentary type. Industrial ore bodies are controlled by WE- and NEE-faults. The NEE fault is main leading controlling structure. The bigger and richer ore bodies are located in the center of pull-fold and interlayer glide zone caused by the NEE fault. The most advantageous mineralizing positions are compound sites of two structures. |
