| Research Abstract |
(1) We obtained many additional samples from the Chengzihe Formation of the Jixi Group of Heilongjiang Province, increased many analytical results, and improved stratigraphic resolution for the international correlation. (2) We obtained analytical samples from the drilling core of the Jixi Group in Bolli City and made a stable carbon isotope analysis. The result leads us to correlate the core with the lower Chengzihe Formation of the group. (3) We made stratigraphic research on the Dabeigou, Dadianzi, Siegayan, and Nantian Formations in Hebei Province. (4) We made sedimentological research on the Lower Cretaceous System in Yanji City, Jilin Province. We obtained the atmospheric pCO2 from the calcareous nodules of the lower Cretaceous. (5) We expanded our analytical methods to the Lower Jurassic in Chonqin City.
