Stable isotope (δ13Cker, δ13Ccarb, δ18Ocarb) distribution along a Cambrian outcrop section in the eastern Tarim Basin, NW China and its geochemical significance
The stable carbon isotope excursion event of SPICE is found in Tarim Basin. Isotopic results confirm the heterogeneous occurrence of Cambrian source rocks. The 13C-enriched oils such as TD2∈ may be from some localized Cambrian source rocks.
