Calcium-isotope fractionation in selected modern and ancient marine carbonates
Thomas Steuber (1,2) and Dieter Buhl (1)
The calcium-isotope composition (d44/42Ca) was analyzed in modern, Cretaceous and Carboniferous marine skeletal carbonates as well as in bioclasts, non-skeletal components, and diagenetic cements of Cretaceous and Carboniferous limestones. In order to gain insight in Ca2+ aq–CaCO3-isotope fractionation mechanisms in marine carbonates, splits of samples were analyzed for Sr, Mg, Fe, and Mn concentrations and for their oxygen and carbon isotopic composition.
