摘要
Early Paleoproterozoic granitoids in the Quanji Massif,NW China provide important information for further understanding the early tectonic history of the Quanji Massif and the relation of the Tarim Craton with the North China Craton.Here we report zircon Hf isotopes as well as whole-rock geochemistry of the two metamorphosed and deformed granitoids exposed in the Quanjisahn and Mohe areas of the Quanji Massif,respectively.
