研究区处于内蒙古东乌珠穆沁旗多金属成矿带,区域有多个1∶5万土壤化学测量综合异常分布,以中低温元素为主,异常规模大,数量多,峰值高。多伦沟矿区分布一个以Ag、Pb、Zn为主的1∶5万土壤测量综合异常,经1∶1万土壤测量查证,分解了多个子异常,子异常以Ag为主,元素浓度分带明显,浓集中心套合程度好,主要子异常区内发育以褐铁矿化为主的蚀变带,蚀变带中赋存以银为主的多金属矿(化)体。经探槽初步揭露控制,蚀变带中银单样最高达1332×10-6,伴生铅锌矿,推断异常由以银为主的多金属矿引起,显示出本区有良好的找矿前景,区域有望形成内蒙古又一重要的银多金属矿带。

The study area lies in the Dong Ujimqin Banner iron polymetallic ore belt. Quite a few 1 ∶ 50 000 geochemical anomalies are distributed in this area and characterized by predominant medium?low temperature elements, large anomaly sizes, large quantities, and high peak values. The Duolungou mining area has a 1 ∶ 50 000 composite geochemical anomaly of Ag, Pb and Zn. The 1 ∶ 10 000 soil survey shows that the anomaly has element concentration zoning and a good consistency with the concentration center, and can be de?composed into several secondary anomalies characterized by predominant Ag. Several alteration belts are developed in secondary anoma?lies, in which there exist polymetallic orebodies dominated by silver. The preliminary trenching demonstrates that the quantity of silver in a single silver sample is up to 1 332×10-6, associated with Pb?Ag orebodies. The anomalies might result from the polymetallic ore?bodies dominated by Ag, suggesting that this area has good prospecting potential and is expected to form another important silver poly?metallic ore belt in Inner Mongolia.
