| 中文摘要: |
| 鄂尔多斯盆地南部是中国重要的砂岩型铀矿成矿带，但地表广泛覆盖第四系黄土，传统地质手段难以有 效揭示深部目标层(侏罗系直罗组)的展布特征。本研究在彬县胡家河 —长武景家河地区完成 AMT测点 102个，结合高精度 GPS定位及抗干扰数据处理技术，旨在查明研究区构造形态、砂体分布及铀成矿潜力， 为钻探靶区优选提供地球物理支撑。 |
| 英文摘要: |
| The southern Ordos Basin is an important sandstone-type uranium metallogenic belt in China， however the surface is extensively covered by Quaternary loess，making it difficult for traditional geologicalmethods to effectively reveal the distribution characteristics of the deep target layer(the Jurassic Zhiluo Forma. tion). In this study，102 AMT measurement points were completed in the Hujiahe(Bin County)– Jingjiahe(Changwu)area. Combined with high-precision GPS positioning and anti-interference data processing technology， the research aims to clarify the tectonic morphology，sand body distribution and uranium metallogenic potential， providing geophysical support for the optimization of drilling target areas. |
