摘要
CN; mso-bidi-language: AR-SA">A study has been conducted on the organic geochemical characteristics of the Lower Palaeozoic carbonate rock samples from the Huanghua Depression, the Bohai Bay Basin.  The results show that the distribution of n-alkanes in chloroform bitumen A is characterized by a single peak type, with the main peak carbon at nC16 or nC18; the OEP is approximately equal to 1 and the ratio of C3122S/(22R+22S) homohopanes is between 0.  580.63, indicating that the organic matter has evolved into a high maturity stage.
