摘　　要：三义号矿区位于天山-阴山纬向成矿带的东端与内蒙-大兴安岭成矿带的复合部位,从地质与地球化学特征等成矿条件来看,属于有利的多金属成矿区带。根据化探结果,确定了本矿区Mo、Pb、Zn、Ag、Cu、Au这6种元素成矿的可能性最大,并圈定出10个元素异常区,其中Ⅰ-Ⅵ元素异常区是比较有前景的多金属成矿区,Ⅶ-Ⅹ元素异常区属成矿条件略差的单金属成矿区。矿区从西到东可划分为A、B、C、D四个地层区带,并根据这四个地层区带地质与地球化学特征,总结了下一步工作的找矿方向。Sanyihao polymetallic deposit is located at the composite part of Tianshan-Yinshan Zonal Metallogenic belt and Iner Mongolia- Xinganling Metallogenic belt. According to the geochemical characteristics that the Mo, Pb,Zn,Ag,Cu and Au these six kinds of elements have great posibility to be enrichment and mineralization, and this area can be delineated out of 10 element content anomaly zones, the Ⅰ-Ⅵ zones are polymetallic ore-forming belts,the Ⅶ-Ⅹzones are single mineral ore-forming belts. This deposit can be divided into A,B,C,D four strata belts from west to east. According to the geological and geochemical characteristics of the four strata belts, summed up the work of prospecting for the next step.
