摘要

The rhythmic coupling of geological events of tectonic movement, magmatism, metamorphism, deposit formation and so on indicate that, for the Ji-Hei composite orogenic belt, the ending time of the Paleo-Asian Ocean tectonic domain is 250~230 Ma; while the starting time of the Pacific Ocean tectonic domain is 227 ~222 Ma. From the view of global tectonics, they are constrained by the forming time of Pangaea （330~230 Ma） and its first splitting time （224 Ma） after it entered the new super-continent cycle （230~0 Ma）.
