Magnetotelluric investigations along the URSEIS profile: first results

An interpretation of an E-W profile of 30 magnetotelluric field stations along the URSEIS transect is presented. The magnetotelluric instruments used covered a period range from 0.2 to approximately 500 s and thus enabled a resolution of shallow and upper crustal structures. After decomposition of t...

Description
Summary:An interpretation of an E-W profile of 30 magnetotelluric field stations along the URSEIS transect is presented. The magnetotelluric instruments used covered a period range from 0.2 to approximately 500 s and thus enabled a resolution of shallow and upper crustal structures. After decomposition of the impedance tensor a 2D interpretation was performed. The model obtained by a 2D inversion displays a conductive zone west of the Main Uralian Fault. It appears to be consistent with a tectonic division obtained by URSEIS seismic studies.[PUBLICATION ABSTRACT]
