摘　　要：在开展1∶5万水系沉积物测量工作基础上,对栖霞地区的元素分布特征、元素富集和分异特征、元素相关性分析、单元素异常特征等地球化学特征进行了初步分析。结合地质成矿背景,根据化探异常和元素成矿特征圈定27处组合异常,并进行了综合分析和异常查证,验证多处异常具有较好的蚀变矿化,其中在AS21区发现5条蚀变带,4条金矿(化)体,说明该区具有良好的找矿前景。Based on stream sediment survey with the scale of 1 ：50000, geochemical characteristics have been pre-liminarily analyzed, such as element distribution characteristics, element enrichment and differentiation characteris-tics ,element correlation analysis and element anomalies. According to anomalies and elements mineralization char-acteristics in combination with ore-forming geological setting, 27 composite anomalies have been circled. Compre-hensive analysis and anomaly verification have been carried o u t, and good alteration and mineralization in many a-nomalies have been verified. 5 alteration zones and 4 gold ore （ mineralized） bodies have been found in AS21 area. It is indicated that there has a good prospecting potential in this area.
