c drive for magnetite formation decreases with
decreasing temperature. Furthermore, magnetite is not predicted to be
part of the serpentinization assemblage at very high water to rock
mass ratios (w/r). These relations indicate that serpentinization reactions
vary with protolith composition, temperature and fluid flux. This
notion is corroborated by magnetic susceptibility–density relations of
partly to completely serpentinized olivine-bearing rocks, which suggest
that reaction pathways of serpentinization are exceptionally variable
