Diversity of the forearc peridotite: evidence from mantle peridotites of the Ust'-Belaya ophiolite, Far East Russia

Abstract

It is well known that there is difference in partial melting degree between forearc and mid ocean ridge peridotite. However, those data of forearc peridotite are almost from the Izu-Bonin-Mariana region. In this study, we tried to reveal the melting processes and the origin of the mabtle peridotite in the Ust'-Belaya ophiolite and state the above problem.
