鄂尔多斯盆地巴音布拉格地区铀成矿远景评价

Bayinbulage Area Uranium Metallogenic Prospect Evaluation in Erdos Basin

鄂尔多斯盆地是中生代发育起来的大型内陆拗陷盆地,面积约25万km2。研究区位于盆地北部的Ⅰ号砂岩朵体上。通过对巴音布拉格地段的铀成矿条件分析,认为该地段无论从铀源、构造、含矿含水层的岩性-岩相条件、层间氧化作用及后生还原作用,还是古气候及古水动力条件,都与纳岭沟、皂火壕铀矿床非常一致或者相似,并且业已发现了重要的矿化线索,因此其成矿远景极为乐观,有望发展成为新的铀矿带。

Erdos basin is a large inland depression basin developed from Mesozoic, with an area of 25×104km2. Bayinbulage area is located in the 1stsandstone lobe in northern Erdos basin. In terms of uranic sources, tectonics, water and ore bearing strata＇s lithological character and lithofacies, interlayer oxidation and epigenetic reduction, paleoclimate and paleohydrodynamic power characteristics, The thesis argues that this area is very similar with Nalinggou or Zhaohuohao uranium deposit, moreover, some important mineralizing clew has been found, therefore, its epigenetic prospect is very optical and it is hopeful to become a new uranic belt.
