Abstract (in english)
   Anisotropy of magnetic susceptibility (AMS) of most rocks is controlled by the paramagnetic (micas) and ferromagnetic (ore minerals) rocks constituent. AMS and bitote preffered orientation measurements were performed on granulites from the Southern Bohemian Massif, which are characterized by a complicated deformation history. The deconvolution of the measured rock AMS led to an extremely prolate ferromagnetic component of the AMS, whereas the bulk rocks AMS as well as the separated paramagnetic AMS are oblate in all cases. The paramagnetic AMS can be clearly related to biotite, whereas the carriers of the ferromagnetic AMS are still unknown. It seems that submicroscopic ore minerals predominate and the optically visible ore minerals plays a minor role. The performed measurements also confirm that the ferromagnetic AMS component should not be neglected, even in low susceptible rocks
