Abstract

Normalized bimodal interpretation of magnetotelluric sounding in the Kyrgyz Tien Shan mountains provides a reliable geoelectric model for this seismic region. The model contains a conductive layer in the lower crust and subvertical conductive zones in the upper crust. High overall conductivity of crustal zones clearly correlates with low-density zones.
