在波西米亚块体西南部做了一条长周期电磁剖面 ,它靠近德国超深钻的位置。用一个二维合成模型对数据做了大体的拟合 ,模型走向东西 ,近地表盖层高度地不均匀畸变。畸变层显示强烈的各向异性 ,优势电导方向为NW -SE至NNW -SSE。讨论了深部区域结构的几个不同的模型 ,其中一个模型可以解释由MT和GDS数据显示的主方向的偏差 ,还讨论了沿特别剖面得到的结果与区域地电结构的关系。 A long-period electromagnetic profile was made in the southwestern Bohemia block near the German ultra-deep drill. The data was roughly fitted using a two-dimensional composite model, with the model going east-west and the near-surface capment highly unevenly distorted. Distortion layer shows strong anisotropy, the dominant conductivity direction NW -SE to NNW-SSE. Several different models of deep regional structures are discussed, one of which can account for the deviation of the main directions as shown by the MT and GDS data and the relationship between the results obtained along the special profiles and the regional geoelectric structure.
