土壤微细粒分离测量方法在查干德勒苏中北部凹陷的试验研究
Applied research of geochemical separation of fine soil particles in the mid-north of Chagandelesu depression Yingen-Ejin basin
摘要
Abstract
For the purpose of exploring the deep uranium mineralization information,an applied research of geochemical separation of fine soil particles was carried out in Chagandelesu depression of Yingen-Ejin basin.Elements of U,Mo,Sr,Pb,etc in the fine soil were analyzed.The research showed that the content of U and other elements conform to normal distribution or approximately normal distribution and U is highly correlated to lithophile elements.The spatial distribution characteristics of U,Mo and Sr were discussed.The weak deep uranium mineralization information could be discovered by manual removal of high-value date in erosion source area.In judging the existential form of U in the weak U geochemical anomalies,the parameter of U/Gd was used in consideration of the content information of Gd.The deep favorable areas for uranium mineralization in research area were predicted.关键词
