摘　　要：几内亚基西杜古省瑟杜地区Kambo河盛产砂金,为了更好地了解该区域金矿的成因以及进一步勘查的需要,有必要调查砂金的来源。通过研究瑟杜金矿区域地质背景、勘查区地质、土壤地球化学及调查砂金现场,并结合探槽等方法,发现砂金和BIF密切相关,砂金可能为BIF残坡积型金矿。Placer gold is abundant in the Kambo River in Sedu District,Quisidugu Province,Guinea.In order to better understand the genesis of gold deposits in this area and the need for further exploration,it is necessary to investigate the source of placer gold.By studying the regional geological background of the Sedu Gold Mine,surveying the geology of the prospecting area,soil geochemistry,on-site surveys of placer gold,and combining with exploration trenches,it is found that placer gold is closely related to banded mag⁃netite(BIF),and placer gold may be BIF residual slope-type gold mine.
