Hafnium–Neodymium Isotope Systematics of Carbonatites from the Guli Massif (Maimecha–Kotui Province, Russia)

Resumo

This work presents new data on the Hf-isotope systematics of baddeleyite and the Nd-isotope compositions of calcite carbonatites of the Guli massif, located within the Maimecha–Kotui province. The Hf–Nd isotope signatures of carbonatites (εHf ~ 10.4, εNd ~ 5.8) indicate that depleted mantle material was involved during magma generation. The application of the Hf–Nd isotope systematics provided an essential tracer for the depleted mantle contribution into the source of carbonatites from the Guli Massif.
