Division And Correlation Of Tectonic Units In The Adjacent Region Of China Northeast And Far East Of Russian

Northeast China is located between the Siberian plate and the North China plate,and the northeast China is next to the Russia.The two countries closely links in terms of geographical and geological units.According to the study in Northeast China and Russia,such as stratigraphy,sedimentary features,deformation style and metamorphic grade of some major block. And divided the tectonic facies of the area. Study area is located in the "Golden Triangle" region which is the Primorye Region of Northeast China, northern Korea and Russia. Tectonic environment of the region is very complex. Including the Paleo-Asian Ocean, the Pacific and the superposition of two tectonic parts. Stratigraphic age from the Archean to the Mesozoic, a larger span of years. In order to understand the nature, the formation and evolution history of different tectonic units, we need to conduct a detail study comparative study.The study area with multiple micro-plate for the synthesis of the main fight the former Mesozoic unified composite plate. The eastern edge of the plate by the effects of the Pacific plate and the subduction of oceanic crust collage. Region experienced a pre-Mesozoic tectonic deformation in different times and in different directions orogeny and plate put together after the Mesozoic and Cenozoic plate tectonic reconstruction, with different tectonic deformation point and complex style. The various geological units within the region before the fight in the synthesis of late Paleozoic as a whole, and after the Carboniferous - Permian marine deposits. Study area is divided into four main plots and four main belt.Include: Gangren-Guanmao block, Jiamusi block, Songnen block and Xingkai block; Heilongjiang proliferative zone, Kaishantun-Qingjin proliferative zone,Jizhong proliferative zone and Kyrgyzstan - Alin orogenic belt. The Gangren-Guanmao block, Jiamusi block,Songnen block and Xingkai block according to tectonic phase divided into basal complex facies and passive continental margin and epicontinental basin facies. Kyrgyzstan - Alin orogenic belt is divided into four parts of the discussion.Thesis with ideas for the tectonic theory, deepening the understanding of existing data and results, drawing in the study area the stratigraphic column and the main tectonic units.Field investigation and laboratory method of combining comprehensive study is used in this paper.Discuss the lithology and stratigraphic features of Yanbian Kaishantun area.Field observations on the outcrop in Yanbian area, lithology observed; indoor specimen identification and analysis, drawing graphic elements determine the tectonic environment.Depth adjacent areas of Northeast China and the Russian division of tectonic facies provides a theoretical basis for the study of plate tectonics in the northeast China. Yanbian region of tectonic facies have a great significance for guiding mineral exploration and mineral development and in-depth understanding of deposit formation mechanism. At the same time, through this comprehensive comparative study of cross-border help to play our geographical advantage for the eastern part of Northeast China planning and development of scientific basis.
