Multiple crust-mantle interactions for the destruction of the North China Craton: Geochemical and Sr-Nd-Pb-Hf isotopic evidence from the Longbaoshan alkaline complex

► We report that the Longbaoshan complex developed in an extensional setting that resulted from subduction of the Paleo-Pacific slab and upwelling of the asthenosphere, and propose that multiple crust-mantle interaction is the essential mechanism for the destruction of the North China Craton. ► Our study has important implications on lithospheric mantle destruction during late Mesozoic in the North China Craton which is invoked by crust subduction and crustal activation.
