Dolomite (/ ˈ d ɒ l. ə ˌ m aɪ t, ˈ d oʊ. l ə-/) is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally CaMg(CO 3) 2. The term is also used for a sedimentary carbonate rock composed mostly of the mineral dolomite (see Dolomite (rock)). An alternative name sometimes used for the dolomitic rock type is dolostone.
Dolomite is used for many of the same purposes as limestone, 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.
Agricultural lime, also called aglime, agricultural limestone, garden lime or liming, is a soil additive made from pulverized limestone or chalk. The primary active component is calcium carbonate . Additional chemicals vary depending on the mineral source and may include calcium oxide .
In the lime industry, limestone is a general term for rocks that contain 80% or more of calcium or magnesium carbonate, including marble, chalk, oolite, and marl.Further classification is done by composition as high calcium, argillaceous (clayey), silicious, conglomerate, magnesian, dolomite, and other limestones.

The region has bedrock mostly of dolomite, covered by glacial till, loess deposits, and outwash. Natural vegetation consisted mostly of tallgrass prairie with occasional mixed hardwood forests, and some savanna in transitional areas between the two. Today, cropland agriculture is widespread, with some pasture and woodland remaining. [3]
Prepared agricultural lime staged near a field in the UK. Liming is the application of calcium- (Ca) and magnesium (Mg)-rich materials in various forms, including marl, chalk, limestone, burnt lime or hydrated lime to soil. [1] In acid soils, these materials react as a base and neutralize soil acidity.
Dolomite – Calcium-magnesium carbonate soil. Flint – Siliceous stone that reflects and retains heat well. The Pouilly-Fumé wine of the Loire Valley is generally produced from flint-based soil and is said to have "gun-flint" smell in the wine. Galestro – Schist based soil found in the Tuscany region of Italy.
Limestone is a raw material that is used globally in a variety of different ways including construction, agriculture and as industrial materials. [102] Limestone is very common in architecture, especially in Europe and North America.
