sed, and a dolomite bed converted back to limestone. This is indicated by a texture of pseudomorphs of m

ineral dolomite that have been replaced with calcite. Dedolomitized limestone is typically associa

ted with gypsum or oxidized pyrite, and dedolomitization is thought to occur at very shallow depths through infiltration of surface water with a very high ratio of calcium to magnesium. Uses Cutting dolomite in 1994. Saaremaa, Estonia. Dolomite is used for many of the same purposes as lim

estone, including as construction aggregate; in agriculture to neutralize soil acidity and supply calcium and magnesium; as a source of carbon dioxide; as dimension stone; as a filler in fertilizers and other products; as a flux in metallurgy; and in glass manufacturing. It cannot substitute for limestone in chemical processes that require a high-calcium limestone, such as manufacture of sodium carbonate. Dolomite is used for production of magnesium chemicals, such as Epsom salt, and is used as a magnesium supplement. It is also used in the manufacture of refractory mate
