摘要
二连盆地是在海西运动所形成的兴蒙弧形造山带东翼内侧所发育的断陷盆地,是中国重要的含油气和含煤盆地,也是铀矿的主要赋存盆地。马尼特坳陷巴润地段位于二连盆地中部,是二连盆地最主要的产铀地段之一。笔者通过分析巴润地段的构造特征、地层特征、沉积相特征,研究其地质、地球物理特性,总结了巴润地段铀成矿控制因素、铀成矿特征、矿体特征,为今后二连盆地古河谷砂岩型铀矿找矿提供了方向。
The Erlian Basin is a rift basin developed in the east wing of the Xingmeng arc-shaped orogenic belt formed by Hercynian movement. It is an important basin which containing oil、gas and coal and also a main deposit basin of uranium deposits. The Barun uranium section of Manit Depression is located in the middle of Erlian basin,and is one of the most important uranium-producing areas in Erlian basin. Based on the analysis of structural features,stratigraphic features and sedimentary facies,the author analyzes the geologic and geophysical characteristics of the Barun area and summarizes the controlling factors of uranium mineralization,uranium metallogenetic characteristics andorebodycharacteristics.,which provide the direction of finding paleo-valley uranium deposit in Erlian basin.
