The Relationship

The eastern part of Heilongjiang province is an important energy base in northeast China, with more than fifty small and medium sized coal basins. The article analyzed the relationship between the basins characteristics and the coal-bearing series deposits in this area. In the early Cretaceous, all the eastern Heilongjiang province area was a large continental margin basin, with the main provenance area located in its west. This makes the coal accumulating effect at that time occurs mainly in the west of the near provenance areas, forming the main coal seam in this province. The second major coal accumulating, mainly in rift basins, happened in Paleocene. In late Cretaceous and Paleocene, the former coal accumulating basin was transformed and damaged because of tectonic forces, so that the current coal-bearing series distribution is characterized by isolated small and medium sized coal basins.
