湖南省通道侗族自治县长界——流源水系沉积物测量地球化学特征及找矿预测

Geochemical characteristics and prospecting prediction of sediments in Changjie-Liuyuan drainage system in Tongdao Dong Autonomous County, Hunan Province

在1:5万水系沉积物测量的基础上,对通道侗族自治县长界-流源地区成矿元素的分布特征、相关性等方面分析,认为区内主要成矿元素为金、银、锑。Au、Ag、Sb异常规模大,峰值高,浓集中心明显、元素套合好,找寻Au、Ag、Sb矿床或矿化体潜力较大。研究区内具有较好的找矿前景,结合水系沉积物异常特征及所处地质环境,为进一步找矿工作指明方向。

Based on the sediment survey of 1:50000 River system,the distribution characteristics and correlation of oreforming elements in Changjie-Liuyuan area of Tongdong Autonomous County are analyzed.It is considered that the main ore-forming elements in this area are gold,silver and antimony.The anomalies of Au,Ag and Sb are large in scale,high in peak value,obvious in concentration center and well-matched in elements.It has great potential to find Au,Ag and Sb deposits or mineralized bodies.The study area has good prospecting prospects.Combining with the anomalous characteristics of stream sediments and the geological environment,it points out the direction for further prospecting work.
