沟系地球化学测量在安源分散流异常检查中的应用

Application of Ditch Sediment Geochemical Survey to the Following-up for Stream Sediment Geochemical Anomalies in Anyuan

沟系地球化学测量是一种新的地球化学找矿方法。在湖南安源分散流异常检查中取得了较好的地质效果：新发现以Ａｇ为主的综合异常，经详查含银最高达４０ｇ／ｔ，具有较好的找银前景．

Ditch sediment geochemical survey is a new method for geochemical exploration ,and was applied to the following-up for the stream sedment geochemical anomalies in Anyuan ,and good geologic results were ac-quired:a synthetical anomaly dominated by Ag has been detected,which has been checked out containing Ag as high as 40g/t.reflecting a good prospect for silver.
