Abstract

The Nd and Sr isotope compositions of Kola carbonatites provide evidence for magma formation through the mixing of two mantle components. In the Sr-Nd correlation diagram in epsilon notation, the Kola carbonatite mixing line has a slope of -0.372 +- 0.082 and passes through the composition of the bulk Earth; this is distinctly different from the East African carbonatite line. Although the enriched component might be similar to one proposed for the East African carbonatites, the depleted component correspondswith the source of the Canadian carbonatites of the Grenville and Superior province which plots off the 1 degrees Nd array.
