regional magnetic anomaly

In connection with Carboniferous, Permian and Triassic rocks, marked by magnetic susceptibility of thousand and dozens of thousands (10-5 SI units) that are located in southern part of Precaspian Depression, samples of these rocks were studied in details, using strongly magnetic samples. The possible effects of anomalous magnetic field were counted on the base of received data.

The magnetic properties of igneous and sedimentary rocks of Lower Carboniferous and Upper Permian, were studied in the core samples from the boreholes, situated in the south of Precaspian depression. The volcanic rocks of Lower Carboniferous are characterized by low (first decades 10-5 SI units), and Upper Permian – by high (hundreds and first thousands 10-5 SI units) values of volume magnetic susceptibility.
