Precise Sr, Nd and Hf isotopic data are important indicators in deciphering the evolution of magmatic rocks and their source. However, such data are difficult to obtain for kimberlite, since these rocks are commonly contaminated by both crustal and mantle materials and also show extensive alteration and weathering following emplacement. In this study, numerous kimberlitic samples from Mengyin in northeast...
Major and trace element, Sr-, Nd- and Hf-isotope, zircon U–Pb and Hf-isotope data are reported for mafic microgranular enclaves and host granitoids from the Xiuyan pluton in the Liaodong Peninsula of the eastern North China Craton, in order to investigate their sources, petrogenesis and tectonic implications. The zircon U–Pb age of the enclaves (211±1 Ma) is identical to that of the host granite (210±1 Ma),...
