Role of carbonatites for Zr–Hf–Nb–Ta and highly siderophile element budgets in the Earth’s mantle – combined stable–radiogenic isotope approach (GA15-08583S)

Carbonatites are mantle-derived silicate magmatic rocks with substantial proportion of carbonate minerals. Lithospheric mantle xenoliths and intraplate alkaline basalts often have extremely high Zr/Hf and Nb/Ta likely origi...
