| 摘 要： | Because of the strong effects of the Caledonian and Indosinian orogenies and Yanshanian magmatism since early Paleozoic time, different types of granites and ore deposits occur widely in the Nanling region of SE China1]. The Guidong complex is situated at the border between the South Jiangxi—North Guangdong post-Caledonian orogenic belt and the Hercynian-Indosinian belt, which is constrained by an E-W regional deep fault (Guidong-Da- dongshan deep fault) and therefore is elongated nea…

| 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. |
