Abstract
The paper presents the results of the study of the anisotropy of the magnetic susceptibility of quartz-magnetite-pyroxene crystal shales of the Pishchansk iron ore structure. The authors measured the value of magnetic susceptibility in 3 petrographic groups (34 samples). The samples were taken at depths of 144–271 m, the magnetite content varies from 0 to 40%. The authors calculated a set of parameters that characterize the distribution of magnetic properties in the samples. The results showed high anisotropy of the magnetic properties of the samples. A significant variation in the shape of magnetic ellipsoids has been established. The correlation of the obtained data with previous studies of acoustic and elastic anisotropy was confirmed.
