Research
My interests
1. Behavior of the transition metal ions among the multiple octahedral sites in silicate minerals occuring under low-grade metamorphism and hydrothermal activity
2. Relationship between the oxidataion state of transition metal ions and hydrogen-bond system
3. Systematic study of Mn-rich hydro-silicates having pentavalent cations, such as As5+, V5+, P5+, in tetrahedral sites
4. Systematic study of hydro-pyroxenoids
5. Crystal chemistry of natural zeolite
Pumpellyite has the two different H-bond systems depending on the oxidation state of cation at X.
