摘　　要：以福建清流-明溪一带为XX区,对1∶5万水系沉积物测量所获得的数据进行分析研究。通过分析水系沉积物的元素特征值,包括平均值、变异系数和元素组合分析等,在以F和Ca为主的元素异常图的基础上,根据组合特征、异常性质,结合异常区的地质背景、成矿地质条件等因素进行圈定综合异常,优选了5处萤石矿找矿远景区,为下一步地质找矿工作提供了依据。Based on the studied area of stream sediment geochemical survey at the Qingliu and Mingxi areas,the 1∶50000 stream sediment geochemical survey data are analyzed.The analysis is carried out on the characteristic parameters of stream sediment elements such as average value,variation coefficient,elemental associations and so on.With elements anomaly map of F and Ca as its priority,the comprehensive anomalies were delineated according to the combination features and abnormal properties,combined with the geological background and metallogenic geological conditions of the abnormal areas.Five fluorite ore prospecting areas were selected to provide the basis for the next geological prospecting.
