Paleoproterozoic S- and A-type granites in southwestern Zhejiang: Magmatism, metamorphism and implications for the crustal evolution of the Cathaysia basement

► The Paleoproterozoic S- and A-type granites association formed at 1.83-1.89 Ga. ► The Paleoproterozoic granites suffered thermal overprinting during 224-231 Ma. ► Both Paleoproterozoic and early Mesozoic magmatism show crustal growth and reworking. ► U-Pb ages, Hf and Nd isotopes provided evidence of existence of Archean basement.
