Igneous geochemistry of the transition elements

The views of Williams were extended by subsequent writers. Curtis (1964) considered the stability of ions in tetrahedral coordination in minerals as well as in octahedral sites. While this approach is applicable to spinels crystallizing from the magma, it does not apply to silicate minerals in which the transition metal ions occupy only six-coordinated sites. Bums and Fyfe (1964) presented crystal field spectral data indicating that cations such as Ni2+ are present in both octahedral and tetrahedral sites in silicate glasses assumed to approximate [Pg.312]
