Carbon Isotope Stratigraphy of the Cambrian System in the Eastern Tarim Basin,China
文献摘要：
The ultra-deep Cambrian System in the Tarim Basin is an important field for petroleum exploration,while fine division of the Cambrian strata remains controversial.In recent years,carbon isotope stratigraphy of the Cambrian System has been established and widely used.Here,we report an integrated profile of carbonate and organic carbon isotopic values(δ13Ccarb and δ13Corg)from cuttings of the Tadong2 Well in the eastern Tarim Basin.Three carbon isotope anomalies of BACE,ROECE and SPICE were recognized on the δ13Ccarb profile.Three apogees and a nadir on the δ13Corg profile and the onset of ROECE on the δ13Ccarb profile were suggested as boundaries of the present four series of the Cambrian System.Suggested boundaries are easily identifiable on the gamma logging profile and is consistent with the previous division scheme,based on biostratigraphic evidence in outcrop sections.Abnormal carbon cycle perturbations and organic carbon burials during the BACE and SPICE events might be related to the reduction and expansion of a huge dissolved organic carbon reservoir in the deep ocean of the ancient Tarim Basin.
