中文摘要: 通过在夏日多地区开展1/5万水系沉积物测量,测试分析了Au、Ag、Cu、Pb、Zn 、Mo等元素,初步归纳了区内6种元素的地球化学特征,认为Ag、Pb、Cu、Mo等元素的富集变异系数较大,表明在该区内元素迁移、富集特征明显,是区内重要的成矿( 指示) 元素;运用多元统计学理论处理、分析相关测试数据,总结区内元素的分异趋势;根据元素地球化学特征,结合地质条件,圈定元素综合异常13处,对重点综合异常HS1综合异常和HS10综合异常进行评述,并据此划分6个找矿靶区,为下步找矿工作提供基础资料。

Abstract:The elements of Au,Ag,Cu,Pb,Zn, Mo are tested and analyzed by conducting the 1∶50000 stream sediment survey in Xia Riduo area of Tibet.The geochemical characteristics of the elements in the research area are summarized preliminarily.The results show that,the enrichment coefficient and variation coefficient of Ag、Pb、Cu、Mo are higher than others,the geological and geochemical reaction of the element migration and enrichment phenomenon are obvious,so,Ag、Pb、Cu、Mo are the ore-forming( instructions) elements.The test data of the above 6 kinds of elements are processed and analyzed based on the Multivariate statistical theory so as to deeply describe the differentiation trends of the elements in the research area.According to the geochemical characteristics of the elements,13 comprehensive anomalous areas are selected.Besides that,the 6 most advantageous prospecting target areas are included and analyzing the geological and geochemical characteristics of the main anomaly HS1,HS10.The abover esearch results can provide basic data for the next step prospecting work.
