Abstract

A sericite from Unnan Mine, Shimane Prefecture, Japan, has a three-layer structure, perhaps similar to three-layer phlogopite and lepidolite, but with various degrees of disorder in inter-layer stacking, in different samples. A classification of polymorphic and disordered forms, showing their relationship, is proposed.
