Quantifying the Composition of Limestone

Limestone is composed of the mineral calcite, better known to chemists as calcium carbonate, small amounts of clay, silt, chert (silica, SiO 2), and dolomite (calcium-magnesium carbonate, CaMg[CO 3] 2).2 To be called limestone, the rock has to have a composition of over 50% dolomite and calcite, though the exact percentages vary widely.
