摘要：
We consider data of study of the parameters of magnetoacoustic emission performed on pyrrhotite from magnetite and pyrite ores from the deposits of the Urals. It is shown that the difference in signals is mainly due to different types of domain structure which forms during the crystallization of pyrrhotite as pinacoids or prisms. Five types of pyrrhotite are recognized depending on the parameters of magnetoacoustic emission. This information can be used as typomorphic features of pyrrhotite of different geneses. (C) 2014, V.
