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.
