Laboratory studies of a three-dimensional magnetic susceptibility from 8 boreholes drilled in north-western part of the Dnieper-Donets Depression were studied for the first time. Average magnetic susceptibility values for each bore-hole and its variability character were investigated. Essential spatial heterogeneity of of the region was revealed. Bore-holes with maximal average magnetic susceptibility values of the rocks occur at the depression margin and near magnetic anomalies. investigations of dry and gasoline-saturated samples in heating process were studied. Experimental study displays different kind of magnetic susceptibility behaviour in dependence on its primary values and rocks composition.
