| 英文摘要 | Along the Proterozoic stratigraphic sections of Jixian, Tianjin, the delta(13)C values of carbonates are mostly negative in the Changchengian (Changcheng System), varying approximately within a range of (0 +/- 1)% in the Jixianian (Jixian System), and have commonly positive values of (2 +/- 2)% in the Qingbaikouan (Qingbaikou System). From Chuanlinggou Formation to Dahongyu Formation, i.e. from ca. 1700 Ma to 1600 Ma, the delta(13)C values of carbonates increase from about -3% to 0%, but oscillate with large excursion in Dahongyu Formation. Two large excursions occur in the Jixianian, one in Yangzhuang Formation and the other in the third sub-member of Wumishan Formation overlaying. These integrated and continuous records of carbon isotope reflect secular variations of delta(13)C value in ancient seawater from ca. 1700 Ma to ca. 800 Ma. The increase and subsequent oscillation of seawater delta(13)C value occurring from the ages of ca. 1700 to ca. 1600 Ma and <1300 Ma may signify two correlative global tectonic events. |
