Dedolomitization is the calcite of dolomite. Usually under erosion unconformity or epigenetic weathering conditions after burial, the dissolution of anhydrite or pyrite produces a SO2-4 solution, which can capture Mg2+ from the dolomite and precipitate calcite, resulting in dolomite being calcite Interpretation, it is often seen that calcite has the illusion of dolomite rhombus, as well as the residual crystals of dolomite.
