Abstract

This paper presents a suit of igneous rocks in the SN-trending geological section with a length of about 200km from Chifeng (Inner Mongolia) to Lingyuan (western Liaoning Province) , to explore the Early Mesozoic geological evolution of the northern margin of North China Craton. The Early Mesozoic (237 ∼206Ma) igneous rocks occur as dyke swarm, diorite, alkali granite, alkali complex, mafic granulite, cumulate and its mantle enclaves that were derived from distinct depths. It is concluded that the lithospheric mantle beneath North China initially strongly interacted with and enriched by crustal materials and that magma underplating induced rapid differential uplift and denudation of continental crust, associated with accretion of the Mesozoic crust and adjustment of the lithospheric structure.
