We describe some unusual metaperidotites that form a mega-block in thermally metamorphosed sediments adjacent to a granitic intrusion in the Nagasawa area, SW Japan, to investigate mobility of elements in a peridotite-sediment-fluid system. The critical mineral assemblage of the metaperidotite is olivine+talc+antigorite, indicating a univariant reaction at ∼500°C. The metaperidotites contain chromian...
The metaperidotites found in the Happo-O'ne region of central Japan are mostly lherzolites to harzburgites with subordinate dunites. Their protoliths originated as a series of refractory residues by near-fractional melting, 15–25% melting in the spinel field, which is confirmed by a HREE melting model of the apparently primary clinopyroxene. These metaperidotites display U-shaped primitive mantle...
