Kwangsian crustal anatexis within the eastern South China Block: Geochemical, zircon U-Pb geochronological and Hf isotopic fingerprints from the gneissoid granites of Wugong and Wuyi-Yunkai Domains

► The gneissoid granites from the Wugong, Wuyi and Yunkai Domains are crystallized at the Kwangsian (410-457 Ma). ► The gneissoid granites mainly originated from the Proterozoic metapelitic and metaigneous source. ► The source have poor input of the juvenile mantle component. ► The crustal anatexis occurred in an intracontinental regime during middle Paleozoic in the eastern South China Block.
