三塘湖盆地层间氧化带砂岩型铀矿成矿条件

Metallogenetic Conditions of Interlayer Oxidation Zone Sandstone Type Uranium Deposit in the Santanghu Basin

三塘湖盆地位于新疆东北部,是一个北西向延伸的山间盆地。三塘湖盆地是形成层间氧化带砂岩型铀矿的有利区域。本文通过分析区域铀成矿地质条件,阐明了铀源条件、构造条件、水文条件、岩相条件、地形地貌及古气候条件以及油气条件对形成层间氧化带砂岩型铀矿的作用。

The Santanghu basin is a NW-trending intermountane basin in the northeast of Xinjiang. Previous research results show that the Santanghu basin is an area favorable for formation of interlayer oxidation zone sandstone type uranium deposit. This paper has a discussion on ore-forming conditions for interlayer oxidation zone sandstone type uranium deposit such as source, tectonic, hydrogeological, lithologic, geomorphic, climatic factor in the Santanghu basin.
