Peridotite xenoliths from Nüshan, Hannuoba and the Subei basin of the North China block have much lower water contents than those from other localities of the world (South Africa craton, New Mexico, Colorado plateau and basin and Range province of USA, South Mexico, French Central Massif and West Kettle of Canada). This difference is probably induced by the thermal erosion of asthenosphere during Mesozoic-Cenozoic period in the North China block.
