We study peridotite xenoliths hosted by Cenozoic basalts from Tianchang.
- •
We report major, trace elements and H2O contents of the olivine, orthopyroxene and clinopyroxene.
- •
The H2O contents are controlled by partial melting rather than metasomatic events.

The Cenozoic lithospheric mantle of the Tianchang was accreted from asthenospheric mantle.
