物化探综合找矿方法在吉林省汪清县复兴地区勘查中的应用

吉林省延边东部地区是中国东部滨太平洋地区重要的金、铜矿化集中区.九三沟金矿位于集中区内,复兴地区属九三沟金矿外围,成矿地质背景优越.在充分研究地质背景前提下,利用水系沉积物测量进行扫面,圈定Au异常6处,而后开展土壤地球化学测量、大功率激电测深和激电中梯测量工作,圈定了若干有利的成矿远景区,择优开展槽探和钻探工程验证,...

APPLICATION OF INTEGRATED GEOPHYSICAL AND GEOCHEMICAL PROSPECTING METHODS IN FUXING AREA,JILIN PROVINCE

The eastern Yanbian area of Jilin Province is an important gold and copper mineralization concentration area in the marginal-Pacific region of eastern China.Fuxing area is in the periphery of the Jiusangou gold deposit,which is located within the mineralization concentration area,with superior metallogenic geological background.Based on a full study of the geological background,the stream sediment survey is conducted for surface exploration and 6 Au anomalies are delineated.Then,through soil geochemical survey,high-power IP sounding and IP intermediate gradient measurement,a number of favorable metallogenic prospects are delineated,among which the superior ones are selected for trenching and drilling verification and 2 gold mineralized bodies are found.Such prospecting results indicate that the application of integrated geophysical and geochemical prospecting methods is feasible and effective,and has reference significance for prospecting similar deposits in the region.
