THE JINNING MOVEMENT OF THE SOUTHERN MARGIN OF THE NORTH CHINA PLATFORM

Based on a great mass of geological facts, the authors have verified that the Jinningmovement extensively affected the southern margin of the North China platform. The intensesyn-tectonic granitic magmatism was intimately associated with the early tectonic evolutionof the Qinling-Dabie orogenic belt and the formation of the Central China high-pressuremetamorphic belt. According to the isotope dating of magmatic activities and sedimentarycovers,it is determined approximately that the time interval of the Jinning movement was950-700 Ma in the area, 50-100 Ma later than that in South China.
