Different response to middle-Palaeozoic magmatism during intracontinental orogenic processes: evidence from southeastern South China Block

Intracontinental orogens are major sites to better understand tectonic regime of plate interior. However, deep response to those processes remains poorly constrained due to the rare exposure of magmatic rocks. Middle-Palaeozoic magmatic rocks from the eastern Yangtze Block (EYB) and Cathaysia Block (CB) of the southeastern South China Block (SCB) have markedly unimodal age distribution with peaks at ~424 and ~438 Ma, respectively. The zircon...
