Discovery of spotted schists from northern Abukuma Plateau and its significance

Although their metamorphic character and geological significance have not been investigated, have been known several met-amorphic rocks, such as Wareyama, Yamagami, and Matsugadaira, along the sheared zone of northeastern Abukuma Plateau. In a part of the Yamagami metamorphic rocks, we have found albite-spotted schists, being very similar to the spotted schist from Sambagawa metamorphic zone, which is of glaucophane schist metamorphism. We, also, found pumpellyite in some rock from the Yamagami metamorphic rocks. Some considerations on the relation between these rocks and the metamorphic character are also described.
