Geology of the petroleum and coal deposits in the North China basin, eastern China

The North China basin evolved initially from a rifted intracratonic graben system on the east-central Sino-Korean platform during the Jurassic and Cretaceous Yanshanian orogeny. The basin reached its maximum stage of development in the Neogene owing to rift reactivation by the Himalayan orogeny. As indicated by geophysical data, extensional rifting within the basin is still active today.
