Tectonics of the Paleoproterozoic Jiao-Liao-Ji orogenic belt in the Liaodong peninsula, North China Craton: A review

A global collisional orogenic event that formed the Columbia supercontinent occurred during 2100–1800 Ma. In the eastern North China Craton (NCC), the Paleoproterozoic Jiao-Liao-Ji orogenic belt (JLJOB), composed of metamorphosed volcanic-sedimentary rocks and intrusions, may have preserved records of the collisional event. Tectonics of the JLJOB thus becomes the key to the understanding of the tectonic evolution of the NCC, and may provide...
