We have selected four carbonaceous chondrites of CO3 type for the study of meteoritic magnetism. We apply the approach regarding carbonaceous chondrites in terms of a magnetic binary system. This model explains meteoritic magnetism as the mixture of two magnetic components: a high coercivity magnetic mineral including SD particles and a low coercivity carrier including MD particles. The construction of the model is based on parameters of magnetic hysteresis loop. We have measured the average magnetic susceptibility per unit mass and made AF demagnetization of NRM (measured using the SQUID magnetometer) to determine the size of the medium destructive field. The thermal experiments to find the Curie unblocking temperatures of magnetic carriers has been also performed. Data indicate differentiations among studied chondrites of type CO3.
