| 摘 要： | 利用远参考与Robust技术手段对新疆北天山地区大地电磁原始资料进行去噪处理,以及静态校正、逐级反演、梯度法、残差法等处理与综合地质解释,取得了较好成效。将该区划分为四棵树凹陷、山前断褶带、北天山推覆带、中天山隆起带四大构造单元,其中北天山推覆带地表裸露石炭系基岩。在推覆断层之下,显示中浅部存在层状低阻异常带,推测为侏罗与白垩系地层,为油气远景区。 |
| 关 键 词： | 北天山推覆带 大地电磁测深 低阻异常带 |

| Abstract: | Using the Far Reference and Robust methods,the magnetotelluric sounding data of Northern Tianshan region in Xinjiang Uygur Autonomous Region are processed and the geological interpretation is given.The region is divided into 4 main tectonical units: Sikeshu depression,the frontal edge fault-fold belt,the nappe belt of northern Tianshan and the middle Tianshan upheaval.The surface of the nappe belt is covered by Carboniferous System bedrock.Under the nappe fault,the abnormal body of low resistivity in middle-shallow layers is discovered,which is deduced as Jurassic and Cretaceous Systems,and it is thought as the main promising oil and gas survey area. |
| Keywords: | Nappe belt of northern Tianshan Magnetotelluric sounding Abnormal belt of low resistivity |
