The paper focused on the spatial distributions of six major metallogenic elements （W, Sn, Au, Cu, Pb, Zn） and their relationship with geological settings based on geochemical data of 1 ： 200,000 stream sediment samples from the Regional Geochemistry-National Reconnaissance （RGNR） project in South China continent. It was found that different element accumulations occur in three metallogenic provinces in the south China continent. Huge amount of tungsten and tin accumulations are mainly distributed in the Cathaysian Block, which are closely related to the metallogenic system of Mesozoic granite province. The anomaly center contains the world＇s largest tungsten-tin metallogenic province in the Nanling region. Huge amount of gold accumulation is mainly distributed around the Yangtze Craton with 6 geochemical provinces, including Qinling, Songpan, the Middle and Lower Reaches of the Yangtze River, the border area of Yunnan, Guizhou and Guangxi provinces, Eastern-Western Hunan, and the border area of Guangdong and Guangxi provinces. The copper accumulation areas are mainly located in the Middle and Lower Reaches of the Yangtze River, West Qinling, the Jinsha-Lancang-Nu rivers, the southwestern margin of Yangtze Craton related to the mantal plume of Emeishan basalts, the border area of Hunan, Guangdong and Guangxi provinces. The enormous lead accumulation areas are mainly distributed in southwest China, the middle and east of Cathaysian orogenic belt （the border area of Guangdong, Guangxi and Hunan provinces, and the coastal metallogenic belt of Southeastern China）. Zinc accumulation areas are mainly located in southwest China and the border area of Guangdong, Guangxi and Hunan provinces. The huge accumulations of elements have made basic contributions to formation of mineralization provinces and the spatial distribution of elements is crucial for us to determine distribution boundaries of the metallogenic provinces, and locate new mineralization targets.
