Laserprobe oxygen isotope analysis of minerals from mantle-derived rocks in eastern China

Oxygen isotope analyses were carried out by the laserprobe technique for mineral separates from mantle xenolith and megacryst in Cenozoic basalts, East China. The results not only give the δ I8O range consistent with that reported for peridotites in the world, but also yield oxygen isotope equilibrium between coexisting minerals.
