| Abstract: | Magnetite/liquid distribution coefficients have been calculated that are consistent with observed variations in contents of V, Sc, Cr, and Ti in lavas from Craters of the Moon lava field, Idaho. In particular, our average distribution coefficient for V (27±8) is in close agreement with that determined experimentally at the temperature and oxygen fugacity appropriate for crystallization of these lavas. Although this value is not very precise, it shows that V contents of at least some calcalkaline series are consistent with generation of andesitic and related magmas from basaltic parental magmas by crystal fractionation, involving removal of appreciable amounts of magnetite.Current address: Geology Department, Rice University.
