Abstract
The paper analyzes the results of magnetic anisotropy measurements of rocks taken from the well “Suputnyk-2” (490–2720 m) of the Kryvorizka ultra-deep well.
The cuberhombic decahedron - shaped biotite, muscovite, magnetite quartzites, gneisses and granites are in the focus of the study. We calculated the intrinsic parameters of the susceptibility tensor, that was used for the initial classification of rocks. According to the shape of the ellipsoid of magnetic susceptibility anisotropy four classes of rocks were defined.
Highly anisotropic rocks comprise 53.8% of the entire collection. The effect of magnetic anisotropy is caused by arrangement of magnetic minerals. The orderly arrangement of magnetic minerals can create the effect of magnetic anisotropy due to ordering of both magnetic axes and domains as well as the texture of minerals and rocks.
