Quick Summary

The North China paraplatform is a geological formation in Asia that formed during the Precambrian Eon. Rocks of Archean age, dating back over 3 billion years, are found here, indicating early continental evolution characterized by intrusions and the formation of greenstone belts. After 3 billion years ago, these early continental nuclei began to coalesce, forming larger landmasses during the Proterozoic Eon. The North China paraplatform's basement structure evolved through collisions and granitic intrusions, with significant tectonic activity shaping its margins.1

Chronological summary
In the North China paraplatform, Chinese geologists have identified a period of intense island-arc magmatism (a process by which molten rock, often formed by the melting of subducted oceanic crust, rises and solidifies to form igneous rock) between 3.5 and 3 billion years ago. Those arcs then…

…called paraplatforms; those include the North China (or Sino-Korean) and Yangtze paraplatforms, the Kontum block (in Southeast Asia), and the North Tarim fragment (also called Serindia; in western China). The orogenic zones consist of large tectonic collages that were accreted around the continental nuclei. Recognized zones are the Altaids, the…
