Early Cretaceous extensional reworking of the Triassic HP–UHP metamorphic orogen in Eastern China

Corresponding to the Early Mesozoic continental subduction between the North China Block (NCB) and the South China Block (SCB), the Tongbaishan–Hong'an–Dabieshan–Sulu massifs are famous for their HP–UHP metamorphism. More than 50% of the HP–UHP Orogenic Belt was significantly reworked by Early Cretaceous extensional tectonics. This Early Cretaceous event with a fast cooling period, at 130–120 Ma, superimposed on the Early Mesozoic HP–UHP...
