| 摘 要： | 巴音塔拉盆地目前探明的铀矿化主要赋存于赛汉组辫状河道砂体中。通过对含矿主岩的岩性特征、后生蚀变与矿化分析研究，认为该区成矿依靠多期次改造形成的后生蚀变岩以及丰富的含铀、含氧水沿断层渗透还原改造而成矿。

| Abstract: | The uranium mineralization discovered in Bayintala Basin occurrs mainly in braided channel sand bodies of Saihan Formation. Through analyzing and studying the rock lithologic features, epigenetic alteration and mineralization, it is considered that the ore formation depends on the epigenetic alteration rock of multi-phased transformation and the infiltration reduction transformation of uranium rich and oxygenated water along the fault. |
