Zircon U-Pb ages and Hf isotopes from the Yishui Complex:implications for the crustal evolution of the Shandong Complex in the Eastern Block, North China Craton

摘要：

The Neoarchean Yishui Complex locates in the eastern margin of the Western Shandong Complex,which is an important component of the Precambrian basement of the Eastern Block of the North China Craton.High-grade metamorphic supracrustal rocks and granitoids comprise the majority of the Yishui Complex.LA-ICP-MS zircon U-Pb dating and Hf isotopic analyses on various lithological units of the Yishui Complex have been carried out in this study and the results therefore provided new insights into the Neoarchean crustal evolution history of the Western Shandong Complex in the Eastern Block of the North China Craton.
