| Abstract: | During the past two decades, at the Research station (Bishkek) more than a hundred magnetotelluric and magnetovariational
soundings were carried out on the Naryn geotraverse that intersects the Tien Shan region from Lake Balkhash to the Tarim Basin
along the 76° E meridian. Integration and complex interpretation of the data of these soundings with improved resolution and
reliability of the geoelectric model of the Central Tien Shan section became an urgent challenge. Our paper presents a complex
of methods for processing and invariant analysis of the electromagnetic data developed for the solution of this problem. Its
application allowed us to validate the choice of the 2D interpretation model for the Naryn Line and to form the adequate ensemble
of the data to be inverted. The developed approaches will also be useful in similar studies in the other mountain regions. |
