Abundance of iron element in mineralogical and planetological objects facilitates their study by Mössbauer spectroscopy technique, which became an useful analytical tool in earth science and mineralogy. Mössbauer spectroscopy gives information about oxidation and magnetic states of iron components in minerals. The precise characterization of the valence state of iron allows mineralogists to solve several current problems of natural inorganic systems.
