The epilogue of Paleo-Tethyan tectonics in the South China Block: Insights from the Triassic aluminous A-type granitic and bimodal magmatism

Triassic aluminous A-type granitoids, mostly peraluminous biotite granites, occur in various areas in the South China Block. Here, we focus biotite granites from three plutons and one granitic dike that provide new insights into the Triassic tectono-magmatic evolution of South China Block. The peraluminous biotite granites from Zhulanbu, Xiaotao and Wengshan plutons all emplaced at ca. 225 Ma and contain Fe-rich biotites. Their high FeOT/(FeOT +...
