Flow, dissolution, and precipitation in dolomite

hydraulic conductivity. A major limitation in laboratory study is the time available for the experiments, because dissolution of dolomite is a (slow) reaction rate limited process at room temperature [Lund et al., 1973]. The main aim of the current experimental research is to understand the evolution of hydraulic conductivity and flow patterns,
