The oxidation states of niobium and tantalum in mantle melts
Niobium K-edge and tantalum L III-edge XANES spectra were recorded for silicate glasses quenched from melts equilibrated at oxygen fugacities (in log units relative to the iron-wüstite buffer) ranging from IW+6.7 to IW-4.3 at 1400-1650°C and atmospheric pressure to 1.5GPa. Niobium and tantalum were...
