Magnetic susceptibility and its anisotropy of rocks from depths down to 8081 m were investigated in dependence of directional stress. Dominant ferrimegnetic minerals were determined using thermomagnetic analysis of magnetic susceptibility. Depth layers, exhibiting unstable behaviour of the studied magnetic parameters under stresses corresponding to actual in situ conditions, were determined and discussed. Rock samples from these strata contain primarily magnetite or mixture of two pyrrhotite phases.
