%X Systematical compositional mapping of olivines from mantle peridotitic xenoliths and/or xenocrysts entrained in basaltic rocks and mafic dykes from eastern North China Craton demonstrates that an apparently temporal and spatial distribution and heterogeneity exist in the Mesozoic and Cenozoic lithospheric mantle.This is entirely consistent with the temporal and spatial heterogeneity and block feature of Mesozoic lithospheric mantle beneath the eastern North China Craton as revealed by the geochemistry of the lithospheric mantle-derived mafic rocks.Different evolution of the Cenozoic lithospheric mantle between the Taihang Mountains and Shandong-Anhui regions mainly reflects the difference in the nature and composition of the melt involved in the interaction between the old refractory lithospheric mantle and the infiltrated melt.Simultaneously,olivine Fo mapping also reveals that the Tan-Lu Fault played an important role in both the Mesozoic and Cenozoic mafic magmatism and the lithospheric evolution in the eastern North China Craton.Furthermore,olivine composition indicates that there still exist some old lithospheric mantle remnants beneath the eastern North China Craton after the lithospheric thinning.Thus,tbe wholesale delamination model for the lithospheric thinning in the eastern North China Craton is difficult to reconcile the available data.
