Dolomite formula.

Ideal, ordered dolomite has a formula of CaMg (CO 3) 2 and consists of alternating layers of Ca 2+-CO 3 2−-Mg 2+-CO 3 2−-Ca 2+ etc. perpendicular to the crystallographic c-axis. Most natural dolomite has up to a few percent Ca-surplus (and corresponding Mg-deficit), as well as less than ideal ordering.Dolomite was the first fertilizer used to prevent hypomagnesemia (Cunningham, 1936).When applied at rates between 100 and 540 kg Mg/ha the Mg concentration of temperate forage is increased by 0.2-1.2 g/kg DM (Table 9.13).These increases in Mg concentration in the forage were associated with a rise in the level of exchangeable Mg in the soil (Jones, 1963b; Simpson, 1964).dolomite. Dolomite - Building Material, Fertilizer, Source of Magnesium: Dolomite is used as a source of magnesium metal and of magnesia (MgO), which is a constituent of refractory bricks. Dolostone is often used instead of limestone as an aggregate for both cement and bitumen mixes and also as a flux in blast furnaces.It was commonly given the end-member formula Ca 2 FeMg(CO 3) 4; Hey (1955) actually used the name ferrodolomite for CaFe(CO 3) 2. The redefinition of the name means the majority of old specimens labelled "ankerite" are now considered to be ferroan dolomite, and true ankerite is quite rare.

Dolomite contains approximately one-half calcium and one-half magne­sium. Frequently equal parts of whiting and magnesium carbonate can substi­tute for dolomite. For example, if the glaze recipes calls for 10% dolomite, 5% whiting and 5% magnesium car­bonate can be substituted. This will not be an exact substitution, but a close match.

I01.5/I11.0 versus x in the range from x = 0.5 to x = 1.5 for non-stoichiometric dolomites with formula Ca2-xMgx(CO3)2: (a) variation of I01.5/I11.0 by changing x in the dolomite formula while ...Dolomite is a calcium element or magnesium element carbonate mineral. CaMg (CO3)2 is the formula unit composition. The trigonal crystal system of dolomite has a rhombohedral habit. Unlike magnesian calcites, calcium and magnesium are divided into complete separate planes in ideal dolomite.
