| 摘 要： | 长白地区处在吉林省东部山区,山高林密,地表大部被玄武岩覆盖,局部又有推覆体覆盖,以往地质工作程度较低.通过地面地质工作,对该区域地质规律及主要岩层、岩性又有了新的认识.应用TEM方法,解决了在高阻玄武岩层下和推覆体下识别、确定古生界石炭二叠系地层,对揭示玄武岩厚度和研究含煤盆地的分布,以及断裂的分布起到了关键性的作用,收到了良好的地质效果.

| Abstract: | The Changbai area is located in the eastern mountain area of Jilin Province,with a dense mountain forest.The most surface in this area is covered by basalt,so it is harder for geological working.Using transient electromagnetic method with high observation precision can be not limited by high resistivity shield,which may achieve a good result for studying the distribution of the coal basin and distribution of the fracture. |

| Keywords: | basalt transient electromagnetic method inferred interpretation |
