Mössbauer spectroscopy has been widely used to determine oxidation states and site occupancies of Mössbauer elements (mainly Fe) and also to characterize chemical bond, charge-transfer and magnetic structure of the elements in minerals. Since Mössbauer measurement using modern instruments and techniques and its data analyses were developed remarkably, it has been easy to apply Mössbauer spectroscopy to various kinds of minerals. Whereas, the recent investigations have revealed that minerals even having relatively simple structure show very complex Mössbauer spectra by the next-nearest neighbour effect or short-range domain structure. In these cases, it is sometimes difficult to fit or assign absorption peaks to each site in the minerals, where some additional methods should be employed. In this paper, the recent applications of Mössbauer spectroscopy to olivines, garnets, pyroxenes, amphiboles, micas and melilites are shown.
