| Abstract: | 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 δ18O range consistent with that reported for peridotites in the world, but also yield oxygen isotope equilibrium between coexisting minerals. |
| Keywords: | equilibrium fractionation oxygen isotopes peridotite xenolith mantle minerals laserprobe |
