Batholith recorded mesozoic multistage tectonic evolution of the South china block: A case study of the guandimiao intrusions

open access: yesFrontiers in Earth Science, 2022
South China is a well-known grand felsic igneous rocks province. However, it is still controversial and not well understood whether the Mesozoic tectono-magmatic pattern is dominated by the subduction of the paleo-Pacific oceanic plate. In this study, we
