| 摘 要： | 为查明二连盆地伊和高勒地区地层结构特征、砂体分布情况,探讨音频大地电磁法(AMT)在玄武岩覆盖区铀矿勘查中的应用效果,项目组在该区域布设两条测线,通过数据反演得到两条剖面的电性分布特征,经推断解释电性剖面,圈定了深部砂体,分析了基底起伏、断裂展布等地质要素。经钻孔资料验证,本次AMT探测结果可靠,可以清晰地反映盆地基底起伏、地层结构及砂体分布情况,为伊和高勒地区铀资源潜力预测及评价提供了重要依据。

| Abstract: | In order to detect the structure of strata and the distribution of sand body,analysis the effectiveness of audio-frequency magnetotelluric method in basalt covered area,two AMT survey line was set in Yihegaole area,Erlian basin.With the inversed resistivity,the distribution of sandstone bodies,basin base and faults were delineated for the uranium exploration.The drilling result verified that the AMT method is accurate and reliable in reflecting the basement morphology,stratum structure and sand body distribution of the basin,which provide important support for the prediction and evaluation of uranium resource potential in this area. |
