华东地区部分花岗岩体铀含量及迁移富集特征研究

Study on uranium contents and the characteristics of migration enrichment in some granitic plutons of East China

通过对华东地区部分花岗岩体铀、钍数据整理,分析和计算得到花岗岩古铀量、活化铀、迁移率数据,进而划分出富铀岩体、铀源体、低富铀岩体、低铀源体、含铀岩体和一般岩体。探讨了花岗岩体铀迁移富集及分布规律,可为该地区寻找与花岗岩有关的铀矿床提供依据。

By sorting and analyzing uranium and thorium data on some granitic plutons in East China,data on paleo content of uranium,active uranium,uranium activiation ratio are calculated out and then uranium rich rock body,uranium source body,low enriched uranium rock body,low uranium source body,uranous rock and general rock body are classified out.Patterns of uranium enrichment migration are discussed,which can provide the evidence for regional exploration of granite-related uranium deposits.
