It is China’s oldest platform. Rocks with isotopic ages older than 3.8 billion years have been found in eastern Hebei Province and Anshan, Liaoning Province. The base of the North China Platform aggregated 1.8 billion years ago during the Zhongtiao Orogeny. A non-metamorphosed layer formed above it in the Mesoproterozoic Era. Approximately 2.4 billion years ago, the original North China Platform disintegrated.
