【 摘 要 】

Put in order the results of measurements of a number of magnetic parameters on samples of titanomagnetite ores Gusevogorskoye deposit by standard methods: magnetoacoustic emission, the Curie temperature, residual and induced magnetization. It is shown that ore magnetism is conditioned by one the magnetic phase, but with the changing content of trace elements. It was noted the presence of maghemite a second magnetic phase in areas with advanced oxidation processes only. Is also noted a wide range of changes by induced (0.37-321.8 A/m) and residual (0.19-7685 A/m) of the magnetizations. Obviously, this is due to both the change in the amount of mineralization and textural-structural features highlight it. These processes led to the formation of different domain structures and predetermine the magnitude and direction of residual magnetization. The residual magnetization of the sample, which is the sum thermoremanent, chemical, crystal, viscous and dynamic magnitizations, due to the possible prevalence of the dynamic magnitization is not always adequately reflect the NRM of titanomagnetite ores in-situ.
