Kegunaan isotop vanadium
- The isotopic abundances of 50V and 51V have been used as an indicator of planetary core formation processes (Fig. IUPAC.23.1). Vanadium is greatly depleted in the Earth’s mantle compared with that in chondritic meteorites (chondrites). It is assumed that the deficit of vanadium in the Earth’s crust is accounted for by its partitioning into the core. The ratios of 50V and 51V have been used as a test of the X-wind model, which accounts for a portion of the extinct radioactive nuclides present in the early Solar System by radiation from the young Sun. 51V is depleted in meteorites compared to Earth.
