Griffioen, Jasper (2017): Enhanced weathering of olivine in seawater. The efficiency as revealed by thermodynamic scenario analysis. In The Science of the Total Environment 575, pp. 536–544. DOI: 10.1016/j.scitotenv.2016.09.008.

"This study aimed to characterise how olivine can weather in seawater, to elucidate the role of secondary precipitation and to ascertain the efficiency in terms of molar CO2 removal per mole of olivine dissolution. Geochemical thermodynamic equilibrium modelling was used, which considered both the variable mineralogical composition of olivine and the kinds of secondary precipitates that may be formed. The advantage is that such an approach is independent from local or regional factors as temperature, related kinetics, mineralogy, etc. The results show that the efficiency falls when secondary precipitates are formed."
