North China Craton and global tectonics

North China Craton, as a distinctive tectonic unit inside of the China, is different from the new established Huatai Craton, and not alike evidently to both the Yangtze and Tarim Platforms. In order to investigate its origin and evolutional history, we regard the all world as an entirety and search the similar terrains in wild scope. After through conscientious correlation and discrimination, it is confirmed that North China Craton is on intimate terms with Siberia Platform and Canada Shield. All the three Cratons were composed of 14 Archean original crust blocks which assembled in late Paleoproterozoic (1.79-2.2Ga) by collisions along orogenic belts at the same time. A unite continent occurred there from that is the author said Paleo-Laurasia Land. Most important geological character of the latter is the identical Mesoproterozoic covering strata which complsed of Changcheng and Jixian Systems in China, Riphean System of Siberia and the sequence A and B in Canada. The breakup of Siberia from Paleo-Laurasia Land was dated in the Early Cambrian. At the beginning of Meso-Cambrian(536Ma), Paleo-Laurasia joined up with Rodinia by a major shearing fault to create the Pannotia that is a widespread supercontinent with short life-span. At that times, the disappearance of Ediacarn fauna and Cambrian "explosion" of skeletalized metazoans also appear to have taken place within the framework of global tectonic event. A previously unexplained identity of North American and Australo-Sinian biofacies is represented by the trilobite fauna of Midde-Upper Cambrian. These problems are readily solved now. At the end of Cambrian(510Ma), Pannotia was disintegrated and divided into Paleo-Laurasia and Paleo-Gondwana. The South Pacific Ocean was opened at the same time. Until the late Ordovician (440Ma±), the North Pacific Ocean was created between both the North China and North American ancient continents by the disintegration of Paleo-Laurasia Land. Review the evolutional history of North China Craton, it coexists with Siberia Platform as a intirety lasted 1300Ma, but with the Canada Shield taken 1400Ma.
