Abstract
New measurements of partition of vanadium (V) between spinel, garnet and a pigeonite-like high pressure (P) pyroxene and magnesian liquids on the mantle solidus as a function of oxygen fugacity (fO2) are presented. The spinel-liquid experiments show an effect of Cr/Al in spinel on partitioning, and further suggest that V exists as V3+, V4+ and V5+ in melts at terrestrial fO2. Vanadium is mildly incompatible in both ‘pigeonitic’ pyroxene and garnet between 4.5 and 6.5 GPa on the mantle solidus. Analysis of the fO2-sensitive partitioning for V between mantle minerals and melts are combined with compositional data from peridotite melting experiments to model the co...
