Possibilities of the AMT method at searches of kimberlite pipes
Last years a number of industrially important low magnetic kimberlite pipes have been discovered. That is why the role electromagnetic method increases at searching works in diamond bearing regions. The audiomagnetotelluric (AMT) sounding method has quite big depths of investigation. Tensor measurements increasing effectiveness of electromagnetic surveys in heterogeneous media are realized.

The Patomsky crater is located in east part of the Irkutsk region (Russia). This geological object has anomaly appearance and is discordant placed relative to hosting geological structure. The crater has been discovered in 1949 during routine geological survey of the territory by geologist V.V. Kolpakov. The drastic investigations of Patomsky crater by modern technology have begun since 2006. The first electroprospecting investigations by AMT method have been carried out in 2008 by «Irk

Investigations of the landfill of industrial wastes by the RMT method
The test site is the landfill of the coal ashes from power plants. The landfill was closed about 5 years ago. Material of the landfill is represented by powder-like particles and granules with the cross sizes from several millimeters up to the first centimeters. Wastes fill in a V-shaped valley of a stream (Fig. 1). The top layer is leveled (difference of altitudes is about 2 m and surface is very smoo
