Geochemical and geochronological study on the Paleoproterozoic rock assemblage of the Xiuyan region: New constraints on an integrated rift-and-collision tectonic process involving the evolution of the Jiao-Liao-Ji Belt, North China Craton

The tectonic evolution of the Jiao-Liao-Ji Belt (JLJB) has been a hot topic into understanding the Precambrian geology of the North China Craton. Although there is a broad consensus that the JLJB is a Paleoproterozoic mobile belt, whether it has experienced a rift-and-collision or a simply arc-continental collision event still remains controversial. The Central JLJB preserves excellent rock exposures of variable ages and therefore represents the...
