Examples of terrain corrections in the VLF method in the Caucasian region, USSR

Abstract

Investigations by the VLF method in mountainous and foothill regions are greatly complicated by rugged-relief effects. A brief account has been given of the available approaches to tackling this problem and a correlation technique has been suggested based on deriving a linear relation between VLF magnetic field intensities and the heights of observation points. The effectiveness of this technique has been confirmed by the results of its application on some Caucasian pyrite deposits.
