Abstract (in english)
   The anisotropy of magnetic susceptibility (AMS) is often controlled by both ferromagnetic (sensu lato) and paramagneti minerals. The anisotropy of magnetic remanence (AMR) is solely controlled by ferromagnetic minerals. Jelinek (Trav. Geophys 37 (1993)) introduced a tensor derived from the isothermal AMR whose normalized form equals the normalized susceptibilit tensor provided that the ferromagnetic fraction is represented by multi-domain magnetite. The present paper shows the clos correlation between these tensors for a collection of strongly magnetic specimens containing multi-domain magnetite. I: addition, acceptable correlation between the tensors was also found for a collection of specimens containing single-domai] magnetite. A new method is developed for the AMS resolution into ferromagnetic and paramagnetic components using th AMR. Some examples are presented of this resolution in mafic microgranular enclaves in granodiorite and in gneisses of th KTB borehole
