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.

本研究采用多种方法来了解低度变质作用和热液活动形成的含水矿物中过渡元素的氧化态、阳离子分布和氢键系统之间的关系。作为这项研究的结果，我透露如下； 1）八面体位点阳离子取代的影响不仅来自于离子半径，还受到八面体拓扑环境的影响；2）系统地了解了绿帘石及其相关矿物和绿帘石的异同，重点关注阳离子取代和八面体的拓扑环境。多面体的拓扑结构，3）很好地研究了过渡元素的氧化态与氢键体系之间的关系，4）天然斜橄榄石的低结晶度，这是并非源自放射性元素，是新发现的。
