Existing studies on marginal sediments show actual fractionation factors indeed approach the theoretical equilibrium fractionation of 70‰ (2,3,4). The pronounced negative conversion factor appears in the PSP region the depths 50 km and below 200 km, indicating that the density anomalies in the uppermost and lower layers in the upper mantle are likely dominated by compositional effects.

As such, the techniques make possible the systematic assessment of the impact of microbial life on subsurface basalts. Other parameters, such as light, nutrient levels, and growth rate, may also affect Mg substitution in biogenic calcite [Delaney et al., 1985; Nu¨rnberg et al., 1996; Lea et al., 1999], but appear to be less important than temperature.

Recent theoretical models suggest that low cell-specific sulfate reduction rates (csSRR) in marine sediments should result in high S-isotope fractionation factors (1).
