摘要/Abstract

摘要： 阿尔哈达铅锌矿床是内蒙古二连浩特-东乌珠穆沁旗多金属成矿带中的代表性矿床之一，矿体主要赋存于安格尔音乌拉组中，呈脉状、透镜状产出，受北西向断裂控制。成矿期断裂发生多次构造活动，形成不同的矿物组合，可划分为石英-毒砂-黄铁矿阶段（Ⅰ）、贫硫化物-石英阶段（Ⅱ）、多金属硫化物阶段（Ⅲ）及少量方铅矿-萤石-方解石阶段（Ⅳ）4个成矿阶段。控矿断裂以左行正断层的运动方式为主，剖面上断裂产状较陡部位、平面上断裂走向偏西部位是矿体产出的有利地段。蚀变带厚度、厚度×品位及矿体厚度高值中心与断裂面产状变化部位基本一致，表明断裂面产状变化地段是矿体赋存及矿化富集的有利位置。矿化富集规律显示矿体与蚀变带均具有向南西侧伏的趋势，表明矿区深部仍有一定成矿潜力。在详细地质调查基础上，结合矿化富集规律，利用数值模拟技术对阿尔哈达铅锌矿床I号矿脉两侧及深部进行成矿远景评价和矿体定位预测，共圈定了6处进一步找矿靶区。

Abstract: Aerhada Pb-Zn deposit is one representative of those in Erlianhot-Dongwuqi polymetallic metallogenic belt. The orebodies occur mainly as veins and lenticular in shape in Angeryinwula formation,and are controlled by the NW striking faults. The ore-controlling faults underwent multiple tectonic activities, formed different mineral assemblages corresponding to the ore forming stages of (Ⅰ) quartz-arsenopyrite-pyrite stage,(Ⅱ) poor sulfide-quartz stage,(Ⅲ) polymetallic sulfide stage, and (Ⅳ) poor galena-fluorite-calcite stage. The ore-controlling faults are characterized essentially by the left slipping normal faults. The positions vertically along the steep trend and horizontally along the westward faults are the favorable place for lead and zinc ore body. The thickness of the alteration zone,the thickness of orebody and its high grade position are all agreed with the structural changing position of the fractures. Both the orebody and the alteration zone have a tendency to SW lateral prostration. According to this ore enrichment pattern, we suggest a further exploration in deep level of the ore mine. Based on a detailed geological investigation and the mineralization enrichment rule above,we evaluated and predicted the favorable locations on both sides and deep level of ore vein 1 in Aerhada deposit by using numerical simulation techniques; and circled six target areas.
