Mineral weathering kinetics are of considerable interest in a variety of fields including hydrology, compositional evolution of groundwater, soil formation, mineral stability, and hazardous waste disposal. Kinetic processes in geochemical reactions involving mineral precipitation or dissolution or both are not well-defined. The techniques reported here eliminate uncertainties inherent in many weathering experiments by introducing a well-characterized mineral surface into a stable solution and monitoring the reaction rate. This procedure yields reproducible results that allow weathering mechanism characterization within a wide range of experimental conditions.
