摘　　要：通过对西藏冈底斯构造带岩矿石中铀、镭测定结果的初步研究发现,铀矿(化)体中铀、镭平衡系数趋于1,而区内铀含量较低的水系沉积物、花岗岩、酸性火山岩等显示较强的偏镭特征。The Gangdise tectonic belt is an important part of the Tethyan tectonic domain ,preliminary study on the dctermination result of 238 U and 226 Ra in the rocks and ores from the belt found that equilib‐rium coefficient of the uranium‐radium tends to 1 in uranium mineralized bodies , but low uranium content rock of river sediments , granite and acid volcanic is characterized by rich radium .

关 键 词：冈底斯构造带 铀 镭 铀镭平衡系数
