英文摘要	The Qinling-Dabie Belt represents the boundary between the North and South China blocks (NCB, SCB, respectively), where ultrahigh-pressure (UHP) rocks are widespread. A structural study in eastern Qinling and zircon LA ICPMS dating of the migmatites that form the core of the Central Qinling Unit allows us to argue that continental collision occurred in the Silurian, before 400 Ma. In the Late Palaeozoic, from the Devonian to the Permian, the northern margin of SCB experienced a continental rifting. From the Late Permian to Middle Triassic, northward continental subduction of SCB is responsible for the development of a high-pressure metamorphism. The age of the UHP metamorphism remains unsettled yet. A two-time genesis, Early Palaeozoic and Early Triassic, is often preferred, but a single Palaeozoic age followed by a Triassic resetting cannot be ruled out.
