摘要: 五道沟地区处于兴安地块与松嫩地块结合部位，多宝山矿集区东部，成矿地质条件优越.该区为森林覆盖区，在该区开展矿产调查过程中，化探方法显得尤为重要.分层次开展区域地质调查、区域地球化学测量和重点区土壤测量，研究该区地球化学特征，确定主攻矿种，圈定重点找矿靶区，取得了一定的找矿成果.通过异常查证新发现铜矿点2处，金矿化点2处，金（铜）矿化信息地10处，找矿线索3处.圈定Ⅰ级找矿靶区3处，Ⅱ级找矿靶区2处.通过研究元素分布规律等，结合成矿地质背景分析，认为该区Au、Ag、Cu、Pb等元素局部富集，Au、Cu成矿的可能性较大，中生代岩浆作用与成矿关系密切.Abstract: The Wudaogou area, located in the juncture of Xing'an massif and Songnen massif and the eastern part of Duobaoshan ore-concentrated area, has favorable metallogenic geologic conditions. The geochemical prospecting method plays an important role in the mineral survey in this forest-covered area. The regional geological and geochemical explorations and soil surveys in key areas are carried out hierarchically to determine the major minerals and delineate the key prospecting targets, which have obtained certain results. Two copper occurrences, two gold mineralization spots, ten gold (copper) mineralization information sites, and three prospecting clues are newly discovered through anomaly verification. Three Level-I and two Level-II prospecting targets are also delineated. By study on the distribution of elements, combined with metallogenic geologic background analysis, it is thought that there is local enrichment of elements such as Au, Ag, Cu and Pb, among which Au and Cu have great metallogenic probability. The mineralization is closely related to Mesozoic magmatism.
