摘　　要：通过分析大章一德亭金矿区龙潭沟矿段1:10000土壤地球化学测量Au、Ag、W、Mo、Cu、Pb、Zn、As、Sb、Bi、Hg元素原始数据统计特征,确定各元素背景值和异常下限,依据异常下限值的1倍、2倍、4倍绘制各元素异常图并对其总结分析;同时利用Excel、SPSS软件对数据进行相关分析、聚类分析以及因子分析,得出Cu、Pb、Zn为主成矿元素的找矿指示元素,结合矿区地质特征全区共圈定’3处综合异常区,对类似矿床的勘查工作具有一定借鉴意义。Through the analysis of the raw data of elements Au,Ag,W,Mo,Cu,Pb,Zn,As,Sb,Bi and Hg in the 1:10,000 soil geochemistry section of the Longtangou Mine in the Great Zhang-Deting Gold Mine,The background value of each element and the lower limit of the exception are determined,and the abnormal maps of each element are drawn according to 1,2,and 4 times of the lower limit of the exception and summarized and analyzed.At the same time,using Excel and SPSS software to analyze the data,cluster analysis,and factor analysis,the ore-finding indicator elements of Cu,Pb,and Zn are obtained,and a total of 3 comprehensive anomaly areas are located in the area based on the geological characteristics of the mining area.It can be used for reference for prospecting and prospecting of similar deposits.
