摘　　要：龙山地区成矿地质条件优越,区内1：5万水系沉积物异常有7处,其中 AS 25 -7 异常元 素组合复杂,浓集中心明显,最具找矿前景.通过对 AS 25 - 7异常进行1：1万土壤测量,共圈定出 3处土壤综合异常,其中 AP 6异常规模及强度较大,在空间上位于侵入岩岩体与火山岩岩体的接 触带上,经地表槽探工程验证,发现并控制铜矿（化）体2条.综合分析认为,龙山地区具有较大的 找矿潜力.The metallogenic conditions in Longshan Region are favorable. Among the 7 anomalies delinea-ted according to the 1 ： 50 000 stream sediment survey in the region,the AS 25-7 element combination anomaly is complex with evident concentration center,which recommends it to be a promising target.3 soil comprehen-sive anomalies were delineated through the 1 ：10 000 soil survey conducted on AS 25-7 anomaly.Of the three, AP 6 anomaly is large in scale and intense and located on the contact zone of intrusion rock mass and volcanic rock mass.Trenching showed that there were 2 copper ore（mineralization） bodies discovered and control
