MIN3P Verification Example: Dedolomitization (comparison of MIN3P to PHAST)

go to MIN3P home page


This scenario simulates the infiltration of slightly acidic water that is undersaturated with respect to calcite and dolomite into an aquifer that contains dolomite. This drives the replacement of dolomite by calcite and subsequently the dissolution of calcite. Figure 1 compares the simulation results from the codes MIN3P and PHAST for an aquifer with an initial dolomite content of 20 vol%. Refer to Calderhead and Mayer (2004) for details on the parameters used in this simulation.
