  Limestone Rock Uses Formation Composition Pictures

  Dolomitic limestone is a rock composed mainly of calcite but some of that calcite has been altered to dolomite Dolomite is thought to form when the calcite CaCO 3 in carbonate sediments or in limestone is modified by magnesium rich groundwater The available magnesium facilitates the conversion of calcite into dolomite CaMg CO 3 2 This
