... demonstrates that the generalized effective- medium theory of induced polarization (GEMTIP) can correctly represent the induced polarization (IP) phenomenon in the artificial rock samples. These samples were manufactured using pyrite and magnetite particles. The results of our study show that the conventional...

... magnetite from hydrothermal alterations associated with the high-grade ore. Introduction The exploration for copper sulphides and gold ore in iron oxide copper gold deposits (IOCG) frequently uses the magnetic method because of the association with minerals having high magnetic susceptibility. However...

... magnetic field maps. The effect of magnetic susceptibility is most often apparent as negative values in the low-frequency, in-phase component of the data, even over rocks of moderate magnetite content. Dielectric permittivity of the range common in geology is most often seen as negative in-phase values...
