Key
Locality type:
Attributing a mineral to the "Sanbagawa belt" (sometimes also written "Sambagawa") is awfully vague, since the Sambagawa metamorphic belt stretches roughly 1,000 km from Ouita prefecture on Kyushu island, then across the whole of Shikoku island, through Tokyo on Honshu island, and on into Chiba prefecture. Nevertheless, several literature references have attributed minerals to the "Sanbagawa metamorphic belt", "Sambagawa metamorphic terrane", etc, and most commonly these refer to the portion in Shikoku island.
