Geochemistry and U–Pb detrital zircon ages of late Permian to Early Triassic metamorphic rocks from northern Liaoning, North China: Evidence for the timing of final closure of the Paleo-Asian Ocean

This paper reports LA–ICP–MS U–Pb zircon ages and geochemical data from the Zhaobeishan Formation on the northern margin of the North China Craton (NCC). These data are used to better constrain the depositional age, provenance characteristics and tectonic evolution regarding particularly the final closure of the Paleo-Asian Ocean in the eastern segment of the Central Asian Orogenic Belt (CAOB). Major, trace, and rare earth element (REE)...
