摘　　要：比利亚谷铅锌矿床是近年来新发现的中型铅锌矿床,通过对其矿区地层、构造、脉岩等的分析,及其矿体特征、矿石特征的详细解剖,认为比利亚谷铅锌矿床充填于得耳布干深大断裂的次一级NW向张性构造(F35、F37)和裂隙中,赋矿围岩主要为中生界侏罗系中统塔木兰沟组安山质凝灰岩和角砾凝灰岩。矿体规模极不均匀,矿体倾角基本陡倾,一般在70°~90°之间。主要矿体在3勘探线附近发生扭转,以东为NE倾,以西为SW倾,矿体常见分支复合、尖灭再现等现象。该矿床具有大中型矿床的成矿潜力,对其矿床特征和成矿规律的研究可以指导下一步找矿。The Viliyagu lead-zinc deposit is a newly discovered medium-sized lead-zinc deposit in recent years.Based on the analysis of strata,structures and vein rocks in the mining area,as well as the detailed anatomy of its orebody characteristics and ore characteristics,it is considered that the Viliyagu lead-zinc deposit is filled in the secondary NW tensioned structure(F35,F37)and fracture of the Deerbugan deep fault.The ore-bearing surrounding rocks are mainly andesite tuff and breccia tuff of the middle Jurassic Tamulangou formation of the Middle Jurassic.The scale of the orebody is very uneven,and the dip angle of the orebody is basically steep,generally in the range of 70°~90°.The main orebodies are torsional near the third exploration line,NE tilting to the east and SW tilting to the west.The orebodies are often found fork,recombination and pointed out.The deposit has the metallogenic potential of large and medium-sized deposits,and the study of its deposit characteristics and metallogenic regularity can guide the next step of prospecting.
