摘　　要：夏河县完洛合—科才一带的水系沉积物地球化学异常特征显示该区金矿具有良好的金矿成矿远景,通过1∶1万水系沉积物测量,发现该区具有Ag、Au、Hg、As、Sb等元素低背景高富集异常特征,结合成矿元素地球化学特征,提出了该地区的找矿标志,指出了找矿方向。Geochemical anomalies of stream sediment in Wanluohe-Kecai, Xiahe County, Gansu show that gold mineralization has a good prospect. According to the survey of scale 1：100 00 stream sediment, the results indicate that Ag, Au, Hg, As, Sb and other elements with low background enriched anomaly high. Combined with geochemical characteristics of ore-forming elements, we proposed indicators for prospecting in the region and pointed out the direction of prospecting.
