Descriptive mineralogical reconsideration of kobeite

Abstract

Kobeite is rare mineral reported in kobe village (old), Kyoto Prefecture. Kobeite is the REE analogue of zirconolite-3T, however study of kobeite is not enough.
In this study, we researched the chemical composition and the crystal stracture of kobeite in well-known localities , Cape Ashizuri ,and Yuge Island.
It is estimated that Kobeite and Zirconolite form the solid solution, and kobeite is the REE analogue of zirconolite-3O.
