摘要
湖北襄樊—福建罗源一千多公里的剖面上作了23个大地电磁测深点。该剖面穿过不同的地质构造单元。 大地电磁测深的结果清楚地反映了剖面内地壳和上地幔的电性结构特征。例如构造单元的形态、边界、断层位置、地壳和上地幔的高导层发育情况等。结果对于了解该区的深部构造背景、探讨深浅构造之间的关系提供了有益信息。
Magnetotelluric measurements were made at 23 sites along more than thousand kilometres long profile from Xiangfan, Hubei Province to Luoyuan, Fujian Province.The profile crosses through different geological tectonic units.The results of MT clearly reflect the characteristics of electrical structure of the crust and upper-mantle, such as shape and boundary of tectonic units, position of fault, development of the high conductive layer in the crust and upper-mantle etc.The MT-results can provide some useful informations for understanding of deep structural background, and inquiring into the relationship between the deep and shallow structures in the region.
