Abstract: The widespread Neoproterozoic magmatism along the Yangtze block carries critical information for understanding the Neoproterozoic evolution of the Yangtze block. In the northwestern margin of the Yangtze block, the Hannan (汉南) intrusive complex includes the Wudumen (五堵门), Erliba (二里坝) and Zushidian (祖师殿) granitoids. Using LA-ICP-MS U-Pb zircon dating method, the Wudumen and Erliba granitoids yielded magma crystallization ages of 785±4 and 778±3 Ma, respectively...
