Relic calcic plagioclase (An88) was found in a clinopyroxene-rich harzburgite from the Mineoka belt, central Japan. It is most likely that saussurite commonly found in the Mineoka peridotites was derived from a calcic plagioclase like the one reported here. Calcic plagioclase was a solidus phase and coexisted with magnesian olivine (Fo90-92), orthopyroxene, clinopyroxene and chromian spinel (Cr/Cr+Al atomic ratio, ca. 0.5). Combined with the age (mainly Miocene) and geographical position of intrusion, the Circum-Izu Massif serpentinites were derived from the upper mantle of the Shikoku Basin. The plagioclase-chromian spinel peridotite is the refractory residue formed only from a low-pressure (10 ?? 5 kb) mantle diapir in the inter-arc or back-arc <br>basins.
