The electrical conductivity structure along the profile of Dagang-Jinghai-Langfang areas

摘要

Magnetotelluric data have been obtained along the profile of Dagang-Jinghai-Langfang areas,The resultsgive an analysis of apparent resistivity,two-dimensional skewness an axes of electrical,and show the relation among str ucture of Jizhong depression,Cangxian uplifted zone and Huanghua depression,the electrical conductivity structu re analysis of the crust and upper mantle.Cangdong and Dacheng faults are great and significant fault,which c ontrol the depression beside uplifted zone,and these type fzult always has uplifted zone of high conductivity st ratum of upper mantle.
