Gas and Dolomite Outbursts in Ore Mines—Analysis of the

Carbonate rock formations consist mainly of the mineral dolomite (CaMg(CO 3) 2) which very rarely occurs in nature in its pure form it is most commonly found with impurities in the form of calcite (CaCO 3) and other minerals such as compounds of iron (FeS 2) magnesium (MgCO 3) and silicon (SiO 2). Dolomite is a rock with a uniform massive compact structure.
