“…Structural similarities between Fe and V oxides have suggested the substitution of V(III) for Fe(III) in Fe-oxides (Taylor and Giles, 1970), and it was shown subsequently that V can replace octahedrally coordinated Fe(III) in the diaspore structure of goethite (Schwertmann and Pfab, 1994;Schwertmann and Pfab, 1996). The incorporation of reduced V species (III , IV) in clays and other secondary minerals provides a useful redox indicator for past anoxic conditions (Gehring et al, 1994;Gehring et al, 1999;Lebedel et al, 2013).…”

“…either as an alteration product of dolomite or as the metamorphic expression of syngenetic Mg-silicates. Several different Mg-silicates (sepiolite, stevensite, kerolite) may form at low temperatures in evaporitic basins instead of dolomite if silica activity is increased by hydrothermal or clastic input (Helgeson et al, 1969;Stoessel and Hay, 1978;Stoessel, 1988;Gehring et al, 1994). Mg-silicates, including talc, may also form from moderate to high temperature (140-380°C) hydrothermal discharge at the seafloor through interaction of hydrothermal silica and seawater magnesium (Lonsdale et al, 1980;Koski et al, 1985;Buatier et al, 1995;Dekov et al, 2008).…”

“…Canil (1999Canil ( , 2002 suggested that V potentially exists as V 2+ , V 3+ , V 4+ and V 5+ in magmas and that the partitioning of V between co-existing silicate melts and oxide or silicate mineral phases at equilibrium was a sensitive function of terrestrial oxygen fugacity. Consequently V has been used as a redox indicator during the crystallization of mafic and ultramafic magmas (Canil, 1999;Toplis and Corgne, 2002), and in Miocene sepiolite (Gehring et al, 1994) and ferricretes (Schwertmann and Pfab, 1994).…”
