摘　　要：A National Science Foundation of China （NSFC） major research project, Destruction of the North China Craton （NCC）, has been carried out in the past few years by Chinese scientists through an in-depth and systematic observations, experiments and theoretical analyses, with an emphasis on the spatio-temporal distribution of the NCC destruction, the structure of deep earth and shallow geological records of the craton evolution, the mechanism and dynamics of the craton destruction. From this work the foUowing conclusions can be drawn： （1） Significant spatial heterogeneity exists in the NCC lithospheric thickness and crustal structure, which constrains the scope of the NCC destruction. （2） The nature of the Paleozoic, Mesozoic and Cenozoic sub-continental lithospheric mantle （CLM） underneath the NCC is characterized in detail. In terms of water content, the late Mesozoic CLM was rich in water, but Cenozoic CLM was highly water deficient. （3） The correlation between magmatism and surface geological response confirms that the geological and tectonic evolution is governed by cratonic destruction processes. （4） Pacific subduction is the main dynamic factor that triggered the destruction of the NCC, which highlights the role of cratonic destruction in plate tectonics.A National Science Foundation of China(NSFC) major research project,Destruction of the North China Craton(NCC),has been carried out in the past few years by Chinese scientists through an in-depth and systematic observations,experiments and theoretical analyses,with an emphasis on the spatio-temporal distribution of the NCC destruction,the structure of deep earth and shallow geological records of the craton evolution,the mechanism and dynamics of the craton destruction.From this work the following conclusions can be drawn:(1) Significant spatial heterogeneity exists in the NCC lithospheric thickness and crustal structure,which constrains the scope of the NCC destruction.(2) The nature of the Paleozoic,Mesozoic and Cenozoic sub-continental lithospheric mantle(CLM) underneath the NCC is characterized in detail.In terms of water content,the late Mesozoic CLM was rich in water,but Cenozoic CLM was highly water deficient.(3) The correlation between magmatism and surface geological response confirms that the geological and tectonic evolution is governed by cratonic destruction processes.(4) Pacific subduction is the main dynamic factor that triggered the destruction of the NCC,which highlights the role of cratonic destruction in plate tectonics.
