The Liao-Ji orogenic belt is a famous Paleoproterozoic orogenic belt in the East Block of the North China Craton (NCC), which extend in NE-SW direction. The geological mass in the Paleoproterozoic Liao-Ji belt is mainly composed of the Liaoji granites and metamorphic volcanic-sedimentary rocks of the Liaohe group (and its equivalents). Throughout the ages, the existence of Early Paleozoic strata has not been found in the Liao-Ji orogenic belt, and the strata we debate were always treated as part of the Liaohe group. In this study, we first identified a set of early Paleozoic sedimentary formation in Xiuyan County in the eastern Liaoning Province. And we found that the strata are not consistent with the Early Paleozoic sedimentary formation dominated by the carbonate rocks of the north China craton. Detrital zircon chronology suggests that the strata may be a geological body related to the evolution of the Gondwana supercontinent. |
