| 英文摘要 | The Jiaobei Massif is a typical and representative Early Precambrian terrane of the North China Craton (NCC) and metamorphosed supracrustal rocks are widespread in this area. These supracrustal units are of great importance for the understanding of the tectonic evolution history of the NCC, as well as the mineralization and responses of the environment. Therefore, various studies, concerning the definition of lithological units, the geochronological framework, metamorphism, mineralization and the implications for environmental evolution, have been carried out. However, several different definitions of the supracrustal units of this region exist which are sometimes confusing for detailed studies. This paper first summarizes the different definitions of the lithological units in order to unravel the distinctions and connections between the different models of definition. We then introduce the research progresses, and discuss the questions and controversies, with a purpose of pointing out future research areas. The Early Precambrian supracrustal rocks of the Jiaobei Massif have been traditionally classified into the Mesoarchean Tangjiazhuang Group, the Neoarchean Jiaodong Group, the Paleoproterozoic Jingshan and Fenzishan groups. Based on the summarization of the research progress as well as the new observation results in the field, the following proposals can be made. (1) Part of the lithologies from both the Tangjiazhuang and the Jiaodong Groups show two episodes of metamorphism, during Neoarchean and Paleoproterozoic, indicating that these rocks were formed before the Neoarchean metamorphism. But their protolith ages have not been well constrained. (2) The metamorphic grade of the Tangjiazhuang Group rocks is normally at granulite facies while that of the Jiaodong Group rocks is usually at amphibolite facies. (3) The BIF-bearing lithologies occurring near Changyi was previously classified as the Xiaosong Formation of the Paleoproterozoic Fenzishan Group. Some geologists suggested that this lithological unit was formed during Neoarchean and should be re-allocated to the Neoarchean Jiaodong Group. (4) Although the scales for most outcrops are small, the Paleoproterozoic (ca. 2. 2-2. 1Ga) bimodal magmatism can usually be seen in this region and they can be seen showing intrusive relations with the lithologies of the Xiaosong Formation as well as the Paleoproterozoic meta-sedimentary rocks of the Yetou Formation, Jingshan Group, implying that rocks of both lithological units are older than the Paleoproterozoic magmatic rocks. (5) Field occurrences of the metamorphosed mafic-ultramafic rocks of both the Jiaodong and Tangjiazhuang Groups tend to imply that they were previously intrusive rocks, rather than volcanic rocks. Based on the occurrences of the Paleoproterozoic bimodal magmatism, the contacting relations between the Paleoproterozoic sedimentary rocks with Archean basement, and in combination with the geochronological framework of magmatism, sedimentation and metamorphism, we propose that the Jingshan and Fenzishan Groups were formed in an extensional basin. This basin is the early response of the Paleoproterozoic mobile belt in this area. The research achievements notwithstanding, questions and controversies still exist because of the multiple episodes of high-grade metamorphism and deformation of this region. Future studies should pay special attention on the definition of the lithological units and their rock assemblages, regional comparison, detailed geochronological framework and tectonics implications and so on. |
