| 摘 要： | 二道河铅锌银矿床的成矿地质条件和产出的大地构造背景优越，其矿区及外围存在隐伏矿体的可能性较大。为深入研究矿区外围的找矿潜力，通过对二道河矿床地质、地球物理和地球化学特征的研究，结合区域成矿背景，利用地质简测、土壤地球化学测量和激电中梯测量相结合的综合信息找矿方法对矿区外围河口林场预测区进行了隐伏矿体预测。结果表明，河口林场预测区具有与二道河矿床相似的成矿地质条件，地球化学和地球物理异常套合程度高。通过靶区优选，区内共圈定出3 个重点找矿靶区和1 个次重点找矿靶区，推测其为铅锌银矿体赋存的最佳部位，为矿区及外围找矿提供依据。

| Abstract: | The metallogenic geological condition and geotectonic background of Erdaohe lead-zinc-silver deposit in Chaihe area are predominant，with tremendous potential for the existence of new concealed ore bodies in mining area and its periphery． In order to study the prospecting potential in the periphery of the Erdaohe mining area， combined with the regional metallogenic background，we investigated the geological，geophysical and geochemical characteristics of Erdaohe deposit． We used the comprehensive information propecting methods of geological preliminary investigation，detailed soil geochemical survey and induced polarization intermediate gradient to predict ore bodies in Hekoulinchang distict of diggings peripheral area． The results showed that the Hekoulinchang forcasting area had the analogous metallogenic geological condition with Erdaohe deposit，and geochemical and geophysical anomalies fited very well． Through the target optimization analysis，three key prospecting targets and a secondary focus prospecting target were totally delineated，which was estimated to be the best positon for the ocurrence of lead-zinc-silver ore bodies． This research is beneficial to the prospecting in mining area and its periphery． |
