Calcium and Magnesium Isotopes in Sedimentary Carbonates

Popis výsledku v původním jazyce

The transition from an anoxic to oxygenated atmosphere was arguably the most dramatic change in the history of the Earth. This ?Great Oxidation Event? (GOE) transformed the biogeochemical cycles of the elements by imposing an oxidative step in the cycles, creating strong redox gradients in the terrestrial and marine realms that energised microbial metabolism. This contribution presents the first calcium (Ca) and magnesium (Mg) isotope records from sedimentary carbonates that formed during the GEO and the global positive carbon isotope excursion, i.e. the Lomagundi-Jatuli d13C event. Results indicate that Ca and Mg isotope data are sensitive to depositional environment, and local elemental cycling, including processes such as seawater evaporation and secondary mineral formation within a paleo-basin.
