Reconstructing South China in the Mesoproterozoic and its role in the Nuna and Rodinia supercontinents

South China, consisting of the Yangtze and Cathaysia blocks (including Hainan Island), is characterized by episodic magmatism and lithospheric-scale tectonism during 1.7–1.0 Ga, and is important in the Nuna and Rodinia reconstruction. Three newly identified Mesoproterozoic magmatic intervals at 1.76–1.60 Ga, 1.53–1.37 Ga, and 1.25–1.05 Ga, were accompanied by three mineralization events at 1.65 Ga, 1.45 Ga, and 1.05 Ga. These events are also...
