| 英文摘要 | Rangnim Massif, located in northern part of the Korean Peninsula, has long been considered as a coherent unit of the Sino-Korean or North China craton. It has been accepted that this massif is the eastward continuation of the Liaonan (South Liaoning) Archean massif in the Liaodong Peninsular, and has the similar Archean basement exposed to the Anshan-Liaobei-Jinan (Longgang) massif to the north. Between the Rangnim and Longgang massifs, a well-known Paleoproterozoic Liaoji rock unit is developed, represented by the Liaohe Group in Liaoning Province and Ji' an and Laoling groups in Jilin Province. However, it is controversial in terms of the tectonic setting of this huge Paleoproterozoic belt, as being either a rift within an Archean continent or a collisional belt between two individual Archean massifs. In this paper, detrital zircons from sands of the Taedong, Chongchon, Songchon, Changjin, Huju, Houchang and Tongno rivers were collected for U-Pb and Hf isotopic analyses, in order to constrain the crustal growth and evolution of the Rangnim massif since all these rivers are originated and run through the massif. The results from 10 samples indicated that the Rangnim massif is mostly composed by 1800 similar to 1900Ma rocks, with little component of Archean material. Field investigation concluded that the Rangnim massif is mostly composed by granulite-facies metamorphosed supracrustal rocks and related granites. Therefore, it is proposed here that the Rangnim is not an Archean massif, but a Paleoproterozoic unit like that of the Liaoji belt. Considered that the analyzed zircons show an Hf isotopic model age similar to that of the whole-rock in the North China craton, indicating a crustal reworking process within the North China craton during the Paleoproterozoic, it is argued that the above Paleoproterozoic unit could be an orogenic belt along the southeastern margin of the North China craton, and we therefore name it as the Liaoning-Jilin-Korea (Liaojichao) Paleoproterozoic orogenic belt. The traditional point of view that the Rangnim is of Archean should be re-considered, and further works are pressingly needed. |
