摘要
利用1∶5万水口幅水系沉积物测量成果,分析研究湘东南水口地区水系沉积物地球化学特征。利用DGSInfo软件对元素分布、单元素异常、元素相关性、异常元素组合等特征进行分析研究,认为W、Sn、Bi、Cu、Ag为区内的主要成矿元素,共圈出15处地球化学综合异常。结合综合异常所处的成矿地质条件进行综合分析,划分为下湾毒砂金锑找矿远景区、联坑—渣村钨钼铜铅锌多金属找矿远景区、曾子坳—鹰咀岩—田心钨锡铜多金属找矿远景区。通过对远景区内的综合异常查证,在下湾AS1综合异常区、联坑AS3综合异常区、曾子坳AS6综合异常区均找到了与异常相关的矿化信息。结果表明,水系沉积物地球化学测量在该区具有较好的找矿效果,为研究区下一步的找矿工作指明了方向。
The geochemical characteristics of stream sediments in the Shuikou area of southeast Hunan Province were analyzed by using the measurement results of stream sediments of the study area at a scale of 1∶50,000.Using DGSInfo software to analyze the characteristics of element distribution,single element anomaly,element correlation and abnormal element combination,it was considered that W,Sn,Bi,Cu and Ag were the main ore-forming elements in the area,and 15 geochemical integrated anomalies were circled.By analyzing the ore-forming geological conditions in which the integrated anomaies were located,it was divided into the Xiawan arsenopyrite-gold-antimony prospecting area,the Liankeng-Zhacun tungsten-molybdenum-copper-lead-zinc polymetallic prospecting area,and the Zengziao-Yingzuiyan-Tianxin tungsten-tin-copper polymetallic prospecting area.Through the comprehensive anomaly verification in the prospecting area,the mineralization information related to the anomaly was found in the AS1 comprehensive anomaly area of Xiawan,the AS3 comprehensive anomaly area of Liankeng and the AS6 comprehensive anomaly area of Zengziao.It is supposed that the geochemical measurement of stream sediments has a good prospecting effect in this area,which indicates the direction for next prospecting in the area.
