中文摘要：
自从新生代， Ordos 块是一个稳定的构造单位。低抵抗力的层是否在中间和这客气的块的更低的外壳存在，是一个待研究的问题。这个工作试图基于越过这个区域沿着侧面收集的 magnetotelluric 数据的解释揭示块的全部外壳的结构。结果证明分层的结构描绘 Ordos 块的外壳，与在大约 20km 的深度的低抵抗力的层，大概与在那里的液体联系了。相反在块的东方和西方上的活跃 tectonics 的区域，在外壳中没有如此的分层的电的结构，并且低抵抗力的地区可能与 decollement 地区有关或可锻砍在外壳中的地区。在在厄多斯·布洛克和附近的区域之间的外壳的电的结构的差别具有意义在大陆分析改变的块的运动和变丑。
英文摘要：
The Ordos block is a stable tectonic unit since the Cenozoic. Whether low-resistivity layers exist in the middle and lower crust of this kind block is an open question. This work attempts to reveal the entire crustal structure of the block based on interpretation of magnetotelluric data collected along the profile across this region. The result shows that a layered structure characterizes the crust of the Ordos block, with a low-resistivity layer at depth of about 20km, presumably associated with fluids there. In contrast, in the areas of active tectonics on the east and west of the block, there are no such layered electric structures in the crust, and the low-resistivity zones may be related to the decollement zones （or ductile shear zones） in the crust. The difference in electric structure of crust between the Ordos Block and neighboring areas is of significance to analyze the movement and deformation of varied blocks in the continent.
