摘　　要：通过对该地区1∶5万水系沉积物测量的16个元素数据进行地球化学信息量化提取,开展单元素异常、组合异常和综合异常研究。据元素性质的相似性、异常特征可分为四组:一类Cu、Pb、Zn、Ag组合,均可为成矿元素;二类Au、As、Sb、Hg组合,主成矿元素Au;三类为W、Sn、Bi、Mo组合,主成矿元素W;四类为Fe、Co、Ni、Mn组合,主成矿元素Fe、Ni。基于异常元素分布位置、叠合性,圈定出了155个综合异常。在对主要异常的解释推断的基础上,结合成矿地质环境分析、矿产检查情况划分4个找矿远景区,进一步优选出12个找矿靶区,为下一步找矿工作开展提供依据。Based on the quantitative extraction of geochemical information of 16 elements from 1∶50,000 stream sediment measurements in this area,the study of single element anomaly,combined anomaly and comprehensive anomaly were studied.According to the similarity and anomaly characteristics of the elements,they can be divided into four groups:The first type of Cu,Pb,Zn,Ag combination,all of which can be metallogenic elements;the second type of Au,As,Sb,Hg combination,the main metallogenic element Au;the three types are W,Sn,Bi,Mo combination,the main ore-forming element W;the four types are Fe,Co,Ni,Mn combination,the main metallogenic elements Fe,Ni.Based on the distribution position and congruence of abnormal elements,155 comprehensive anomalies were identified.On the basis of the interpretation and inference of the main anomalies,combined with the analysis of the metallogenic geological environment and mineral inspection,4 prospecting prospect areas are divided,and 12 prospecting target areas are further selected to provide the basis for the next prospecting work.
