摘　　要：额尔古纳地区农牧场一队位于上库力地区956.6高地幅南部,根据1∶5万土壤地球化学测量结果,分析了区内17种元素地球化学参数特征及元素相关性,发现元素异常主要集中在佳疙疸组、石炭纪侵入岩以及侏罗纪侵入岩中,主要有利成矿元素为Au、Pb、F、Ag、Bi、Sb、As、Hg、Mo、Zn,可重点围绕其开展找矿评价工作。研究区内元素地球化学异常主要受区域构造及石炭纪、侏罗纪中-酸性岩浆岩控制。根据异常特征及地质背景,圈定出综合异常7处;在此基础上,结合成矿地质条件和找矿标志,初步划分成矿远景区2处,即上库力农牧场第一生产队萤石矿找矿远景区和敦达库力萤石矿找矿远景区,为下一步矿产勘查工作提供了地球化学依据。The ranch of the first team in Erguna region is located in the southern region of 956.6 highland of Shangkuli area.Based on the results of 1:50,000 soil geochemical survey in this study area,the geochemical characteristics and relationship of 17 elements in this study area were analyzed.The result shows that the elements abnormalities are mainly concentrated in the Jiageda formation,Carboniferous intrusive rocks and Jurassic intrusive rocks.The major metallogenetic elements are Au,Pb,F,Ag,Bi,Sb,As,Hg,Mo and Zn,the prospecting and evaluation work mainly rely on these data.The geochemical abnormalities of elements in this area are mainly controlled by regional structure and intermediate-acidic magmatic rocks in the Carboniferous and Jurassic.Seven comprehensive abnormalities were delineated according to the abnormal characteristics and geological background.On this basis,combined with geological conditions and prospecting indicators,two ore-forming prospecting areas have been preliminarily divided,namely the fluorite metallogenetic prospective area of Shangkuli ranch of the first team and Dundakuli fluorite metallogenetic prospective area.it provides geochemical basis for the further prospecting work.
