Abstract: The Seluohe Group is located in eastern portion of the northern margin of the North China craton, Seluohe-Huajiling area, Jilin Province, China, and has been considered to be the Meso-Neoproterozoic metamorphic strata for long time. Based on the recent filed investigation and dating, however, the original Seluohe Group is actually composed of metamorphic strata and deformed granites with different ages, geneses, tectonic styles and metamorphic grades, so this lithostratigraphpic unit is no longer valid and should be dismembered. The original Seluohe Group contains at least four parts: Late Archean metamorphic rocks (zircon SHRIMP protolith ages 2 517-2 534 Ma), Late Paleozoic metamorphosed volcanic-sedimentary strata (zircon SHRIMP 252 Ma), Permian gneissic granitic complex (zircon SHRIMP 260 Ma), and Jurassic mylonitized granites (zircon SHRIMP 168 Ma). The so-called Seluohe Group-complex defined previously in the Seluohe area is in fact a suit of low-grade metamorphosed volcanic-sedimentary sequences which were probably generated during the late Paleozoic, or a complex composed of tectonic slices with various ages.

Key words: Seluohe Group, age assignment, Jilin Province
