| Research Abstract |
Multi-approach to understand the relationship among the oxidation state of the transition elements, cation distribution, and hydrogen-bonding system in hydrous mineral formed by low-grade metamorphism and hydrothermal activity was carried out in this study. As the results of this study, I revealed as follows ; 1) the influence of cation substitution at octahedral sites was not only derived from ionic radius but also topological environment of octahedra, 2) The similarity and difference of pumpellyite and their related minerals, and epidote were systematically understood to focus on the cation substitution and the topology of polyhedra, 3) Relation between the oxidation state of transition elements and hydrogen-bonding system was well investigated, 4) the low-crystallinity of natural clinozoisite, which is not derived from radioactive elements, was newly discovered.
