The first data on Sm and Nd isotopes of the Neoarchean komatiite-tholeiite association from the L’govsko-Rakitnyanskii greenstone belt of the Kursk magnetic anomaly (Central Russia)

The first data on Sm and Nd isotopes of the Neoarchean komatiite-tholeiite association from the L’govsko-Rakitnyanskii greenstone belt of the Kursk magnetic anomaly (Central Russia)

The LgovskoRakitnyanskii (Belgorod skoMikhailovskii) belt mainly composed of metat holeiites and hosting unique iron deposits of Paleoproterozoic age is the most well studied. Metamorphosed komatiitebasalts were established in its central part. Their investigation is of special importance for unders...

Zusammenfassung:The LgovskoRakitnyanskii (Belgorod skoMikhailovskii) belt mainly composed of metat holeiites and hosting unique iron deposits of Paleoproterozoic age is the most well studied. Metamorphosed komatiitebasalts were established in its central part. Their investigation is of special importance for understanding of the composition of the Archean subcontinental lithosphere and mechanisms of tectonic evolution of the Sarmat segment within the East European cratonm
