Factors contributing to high delta C-13 values in Cryogenian limestones of western Mongolia
- Abstract:
-
A geochemical study of Cryogenian (late Neoproterozoic) limestones from western Mongolia is presented, including δ13C (carbonate and kerogen), δ18O, 87Sr/86Sr and rare earth element data. Carbon isotope compositions confirm the existence of anomalously high δ13C in Cryogenian seawater with δ13Ccarb> + 10‰. Positive δ13C excursions are explained conventionally by elevated rates of organic carbon burial. However, four additional factors appear likely to have contributed to δ13C excursions du...
