What is dolomite material? There are two general classifications of stone. The two classifications are siliceous and calcareous. Siliceous stones are composed of silica (SiO2) particles and are very durable. Examples are granite, slate and sandstone. Calcareous stones are composed mostly of calcium carbonate and are softer than the siliceous materials. Examples are marble, travertine and limestone. Jerusalem Stone is a dolomite which falls in the calcareous stone catagory. Dolomite stone (or Dolostone) are those which contain more than 50% carbonate minerals of which over half are dolomite minerals (calcium-magnesium carbonate). Dolomite is considered carbonate rock.
