ABSTRACT: An apparatus for studying the surface dissolution of soluble rocks was constructed to investigate the effect of flow velocity on the surface dissolution rate of rocks containing gypsum and anhydrite. Results reveal that the calcium concentration reaches a saturation status which is independent of the flow velocity. In addition, the presence of other soluble materials affect the rate of solubility. Another important conclusion was that the dissolution constant rate is invariable at a specified upper limit of flow velocity. A generic relation for the dissolution of materials consisting of different compositions was proposed. Finally, it was suggested that the concentration of the soluble materials can be quantified and correlated using the electrical conductivity of the solution.
