摘　　要：河南省砂金矿床广泛分布于黄河、长江两大水系的支流中,具代表性的有淅川寺湾及嵩县高都川两矿床,其成因类型分属于河床-河漫滩型与阶地型两大类。矿体展布形态与全新统地层分布状态一致,为近水平沿现代河流边部赋存的长条带状。在地质找矿方面,在两大水系交汇处、河流地形的缓坡以及河流的内湾一侧均为寻找砂金矿床的有利区段。gold placers in Henan province are widely distributed in tributaries of the Yellow and Yangtze River.The Siwan gold placer in Yichuan county and the Gaoduchuan gold placer in Songxian county are the two representatives belonging to channel-floodplain type and terrace type respectively.Distribution of the gold placers is coincided with that of Holocence strata and they occur as sub-parallel zones along modern rivers.The intersections of rivers,the gentle slopes of the river terrace and the inner curves of rivers are the prospecting targets.
