We consider the parameters of the magnetoacoustic-emission (MAE) effect in magnetites from the ores of the Urals and West Siberia. It has been shown that the differences in signals are related to various types of the domain structures of samples, whose fixity is determined by the formation conditions of magnetite and the effect of superposed physicochemical processes. On the basis of the field parameters, the magnetites have been divided into three types depending on the area of magnetic fields with MAE. These parameters can serve as the typomorphic features of magnetites of different genesis.
