| 摘 要： | 通过对穿过龙门山逆冲构造带中段松潘一中江大地电磁观测资料的处理和反演解释,揭示了松潘-甘孜褶皱带、龙门山及川西前陆盆地30 km深度的地壳电性结构,发现龙门山-松潘地壳15～20 km深部存在西倾连续的壳内商导层,大地电磁测深结果明显显示龙门山深部逆冲推覆构造特征.龙门山深部电性结构初步研究,对于分析其与相邻构造单元的关系,研究青藏高原东缘陆内造山带深部地球动力学过程都具有重要理论意义.

| Abstract: | By processing,interpreting and inversing the magnetotelluric observation data obtained from Songpan-Zhongjiang passed through the middle section of the Longmen thrust belt,this paper reveals 30 km deep crust architecture of the Songpan-Ganzi fold belt,Longmen Mountains and West Sichuan foreland basin,and finds the west inclined successive high conductive layer in the crust of 15~20 km of Longmen Mountains.The magnetotelluric sounding result evidently demostrates the features of the Longmen thrust belt in th... |
