    Abstract

    Single zircon LAM-ICPMS U-Pb dating indicates that the Guidong granitic complex is a multistage batholith formed during Indosinian-Yanshanian time. The Luxi body (239 ± 5 Ma) and the Xiazhuang body (235.8 ± 7.6 Ma) intruded during Indosinian time, whereas the Aizi body (160.1 ± 6.1 Ma) and the Siqian body (151 ± 11 Ma) formed during Yanshanian time. Inherited zircons (1275-2137 Ma) in the Xiazhuang body imply that at least part of the source rocks of the Guidong complex are from the Proterozoic basement of southeast China. Detailed single zircon LAM-ICPMS U-Pb dating results provide important evidence for understanding the evolution, tectonic setting and mineralisation of the complex.
