Geochronology, geochemistry and Nd–Hf isotopes of the Xiaokouzi granite from the Helanshan complex: Constraints on the Paleoproterozoic evolution of the Khondalite Belt, North China Craton
Precambrian Research(2018)
摘要
•LA-ICP-MS zircon U-Pb dating yield 2023 ± 11∼2034 ± 14 Ma for the Xiaokouzi granite.•The ∼2.0 Ga magmatic rocks were the potential provenance of the Khondalite Belt.•The khondalite protoliths were most likely deposited on active continental margin.
