Figure 5: Experimentally determined serpentinization rates.
From: Effect of water activity on rates of serpentinization of olivine
(a) Logarithm of the serpentinization rate (red diamonds) as a function of the logarithm of the activity of water. Each red diamond represents the result obtained from an individual SFI. The rate equation predicts a log rate constant of −7.24 and an apparent reaction order of 103. (b) Comparison of results of this study at 280 °C with experimentally determined reaction rates from the literature20,21,22,23,24 plotted as a function of temperature. Most of the previous experimental studies have used pure water20,21,23,24 and a few others used different fluid compositions22,23,25.
