The application of “511” synthetic prospecting methods to mineral explorations——An example from Huangbi-Lizikeng lead-zinc-silver-copper metallogenic belt in northern Wuyi mountain area

The 1:200 000 lead-zinc-silver-copper mineralization forecast was conducted in Mesozoic igneous district in Huangbi-Lizikeng area, Northern Wuyi. After optimized the prospecting targets areas, anomalies inspection, geological survey and exploration work applying the "511" synthetic prospecting methods were followed. The basic steps are follows:first we did layout of 1:50000 stream sediment geochemical survey in order to decompose the regional anomalies gradually narrowing the prospecting targets areas for finding the favorable mineralization areas. Then we conducted the 1:10000~2:0000 survey of soil geochemistry in the favorable mineralization areas in order to find all types of secondary anomalies related to mineralization. Finally we found lead-zinc-silver-copper- molybdenum mining areas of great prospects in Shengmikeng, Caijiaping and Jinzhuping. The methods we used showed notable effects in mining prospecting.
