Abstract
Peridotite xenoliths from Noyamadake represent ca. 7 Ma samples of relatively dry mantle wedge that equilibrated with a high geotherm. Re-Os isotopic systematics suggest presence of older continental lithosphere and help to constrain the composition and behaviour of Re and Os in the mantle wedge.
