Reaction Kinetics of Primary Rock-Forming Minerals under Ambient Conditions

This article firstly discusses the general techniques for measurement of dissolution and precipitation rates of rock-forming silicates and carbonates, and then, seven of these nine factors are discussed sequentially. Full discussions of the last two phenomena, transport and biologic processes, are not included. Throughout the article, it also discusses how surface complexation models can now be used to understand the reactive sites on mineral surfaces. Nonetheless, the intent here is mostly to emphasize simpler rate equations that emphasize solution chemistry instead of surface chemistry because these are often used in reactive transport codes. Techniques to predict the rates of mineral dissolution for mineral compositions where data are unavailable are summarized.
