C-O isotopic analysis of carbonate sampled from the Mesoproterozoic Gaoyuzhuang Formation in the Kuancheng Area, Hebei Province, demonstrates that the original components of the carbonate have been well preserved. δ¹³C and δ¹⁸O ranges from -5.03‰～0.07‰ and -9.92‰～-4.12‰, respectively, with averages of -0.90‰ and -6.58‰, all of which are lower than those of Jixian section in Tianjin and Ming Tombs in Beijing by previous workers. The results show that the δ¹³C value in the studying area is mainly influenced by the oxidation degree and the buried rate of organic carbon, as well as the quantity of the blue green microalgae.
