摘要
以产铀盆地所处大地构造位置、形成演化及铀矿化成因特征为基础,将中央亚洲活动带及邻区主要砂岩型铀矿床分为5种类型,分析了不同类型铀矿床的分布规律,对其产出构造地质背景和铀矿化特征进行了讨论,指出了我国西北地区盆地动力学的特征、主要找矿类型和含矿层位。
Based on the study of geotectonic setting, formation evolution model and metallogenic characteristics of uranium productive basins, important sandstone-type uranium deposits in Central Asian mobile belt and neighbouring area are divided into five types. The statial distribution pattern of different sandstone-type uranium deposits is analyzed in detail. Geotectonic setting and metallogenetic characteristics are discussed. Finally, the characteristics of basin geodynamics, prospecting type and ore-bearing stratigraphy in Northwest China have been proposed.
