dedolomite
dedolomite Limestone formed by the replacement of dolomite by calcite in a carbonate rock. This replacement occurs mainly when a dolomite is flushed through by meteoric or sulphate-rich waters. A characteristic feature of dedolomite is the presence of dolomite-shaped, rhombohedral crystal forms now occupied by calcite pseudomorphs.
