The Dolomite Mountains, Italy''s Alpi Dolomitiche, however, are a special case: the rock in them was originally simple calcium carbonate made from dead corals and seashells on the seafloor. Only later was it transformed into dolomite through the orderly addition of magnesiumand through the action, McKenzie suspects, of sulfatereducing bacteria.
Dolomite. The term dolomite is used both for the mineral dolomite (calcium magnesium carbonate [CaMg(CO 3) 2]) and for the rock dolomite, which consists mostly of the mineral dolomite. Dolomite rock is sometimes termed dolostone to distinguish it from the mineral dolomite, but the more confusing terminology is the more prevalent.

For example, a high quality pelletized lime source may have a neutralizing value of 85. If this is the case, the lime rate can be reduced to 78% of what would be recommended for bulk ag lime. This is calculated by dividing the average neutralizing value of ag lime by the neutralizing value of the pelletized lime being used (67 "85= 0.78).
Dolomite can also serve as a host rock for lead, zinc, and copper deposits. In the chemical industry, dolomite is used as a source of magnesia (MgO). The steel industry uses dolomite as a sintering agent in processing iron ore and as a flux in the production of steel.
