1Major tectonic units of the North China Craton and their Paleoproterozoic assembly显示文摘The basement of the North China Craton can be divided into the Eastern and Western Blocks and the Central Zone (Trans-North China Orogen). The West Block formed by the amal-gamation of the Ordos Block in the south and the Yinshan Block in the north 1.9—2.0 Ga ago. In 1.8—1.9 Ga, the Eastern and Western Blocks were amalgamated along the Central Zone to form the North China Craton.赵国春 孙敏 SimonA.Wilde 2003Science China Earth Sciences2003,46,1:64
2Identification of Mesoproterozoic zircons in a Triassic dolerite from the Liaodong Peninsula, Northeast China显示文摘Thick Neoproterozoic strata are widespread in the Dalian region, Liaodong Peninsula, Northeast China. SHRIMP zircon U-Pb dating of dolerite intruded into Neo-proterozoic strata gives its emplacement age as 211±2 Ma. However, abundant 0.9—1.1 Ga zircons are identified in the dolerite. The age of 1125±38 Ma corresponds with the Grenvillian collisional event. The zircons of 904±15 Ma ages have high Th/U ratios (1.31—2.25) and magmatic oscillatory zones, being possibly related to later magmatism induced during amalgamation of Rodinia.YANGJinhui WUFuyuan ZHANGYanbin ZHANGQi SimonA.Wilde 2004Chinese Science Bulletin2004,49,18:23
