Soil Geochemical Characteristics and Prospecting Prediction of the Ranch of the First Team in Erguna Region
摘要
Abstract
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.关键词
