摘要
对平和霞寨—南胜地区水系沉积物测量数据进行了处理分析,根据直方图,分析了元素的地球化学分布特征;通过因子分析对元素共生组合特征进行了探讨,方差极大旋转因子解处理结果显示Mo-W-Bi-Sn、Pb-Zn-Ag-Mn-Cd、As-Sb、Co-Mn、Au-Cu 5组元素组合异常区域套合性较好。研究发现Pb、Zn、Sn、Mo、Au、Ag为区内具有一定找矿前景的元素。根据区内成矿地质环境、水系沉积物地球化学,圈定找矿远景区6处。
This paper processes and analyzes the metrical data of the stream sediment of XiazhaiNansheng Water System in Pinghe County,Fujian,and analyzes the geochemical distribution characteristics of the elements via histogram.It also discusses the features of the elements＇ paragenetic assemblage through factor analysis.The processing results of varimax rotation factor solution show that the five groups of element associations of Mo-W-Bi-Sn,PbZn-Ag-Mn-Cd,As-Sb,Co-Mn and Au-Cu have good abnormal regional combination feature.The study also finds that Pb,Zn,Sn,Mo,Au and Ag are the elements with certain exploration prospect in this region,so it determines 6 exploration prospect areas and proposes exploration direction for future work in line with the factors such as mineralizing geological environment and stream sediment geochemistry,etc.in the region.
