This study was partly supported by a Grant-in-Aid (KAKENHI; No. 15340193 to ME) from the Japan Society for the Promotion of Science. Technical supports were provided by Drs. M. Oshima, Y. Hatsukawa and Y. Oura, to whom we are deeply grateful. Komatiite samples were donated by Prof. M. Humayun, to whom we are thankful. The manuscript was greatly improved by careful and through reviews by J. Mizera, G. Sun and an anonymous reviewer, to whom our thanks go. This work was conducted under the Interorganization Atomic Energy Research Program in an academic collaborative agreement between the JAEA and the University of Tokyo.
