英文摘要	The Paleoproterozoic Jiao-Liao-Ji Orogenic Belt in the eastern North China Craton provides evidence of the evolution from the early rifting and ocean opening to the final collision of the Longgang and Nangrim blocks. However, it is still open to debate, and thus controversial, as to whether the Jiao-Liao-Ji Orogenic Belt formed by closure of a rift without subduction or from an ocean with subduction. Based on detailed field mapping and structural analysis on a micro/meso-scale of the Liaohe Group in the center of the Orogenic Belt, we define at least four phases of deformation and metamorphism. S-0 is bedding formed during deposition of the lower Liaohe sediments in the Liaohe back-arc basin. During D-1 deformation an early greenschist facies event (M-1) was associated with a bedding-parallel Si metamorphic foliation, penetrative axial planar foliation, micro-to meso-scale folds (F-1), and an L-1 lineation, all formed during accretion, probably in a trench-subduction setting. An M-2 metamorphism took place during medium-pressure Barrovian-type amphibolite facies conditions and associated D-2 deformation that gave rise to major thrusts, open-isoclinal folds and a well-developed crenulation cleavage during exhumation of high-pressure and high-temperature rocks and collision of the Longgang and Nangrim blocks. M-3 metamorphism at sillimanite (M-3(1)) and cordierite (M-3(2)) grade was associated with D-3 deformation that produced regional gentle re-folds related to post-collisional exhumation of the Orogenic Belt. An M-4 retrograde metamorphism and D-4 deformation gave rise to a weak foliation that can be correlated with late Cretaceous extension that affected the whole eastern North China Craton. We present new isotopic ages (LA-ICPMS U-Pb zircon) of a granitic vein (2162 Ma), a pegmatite (1840 Ma), and a very late granite (114 Ma) that are integrated with relevant published data. Accordingly, the formation age of deformation and metamorphism was set up, and at last, a modified tectonic model was presented.
