摘要
In this paper, the authors link cathodoluminescence (CL) images, U-Pb ages, and trace element compositions obtained from distinct zircon domains of complex zircons to unravel the origin, polyphase protolith and metamorphic ages of TTG gneisses and granitic gneisses in Jiaobei terrane. A combined study of previously geochemical and Nd isotope data provides insight into the nature of TTG gneisses and granitic gneisses in the Jiaobei terrane. The results indicate that a significant continent-continent collision event did take place within the Jiaobei terrane at Paleoproterozoic.
