Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg(CO3)2. It is the number one thing of the sedimentary rock called dolostone and the metamorphic rock known as dolomitic marble. Limestone that includes a few dolomite is known as dolomitic limestone.

Physical Properties of Dolomite
The physical properties of dolomite which are beneficial for identification are offered in the desk on this page. Dolomite has 3 guidelines of best cleavage. This may not be glaring while the dolomite is quality-grained. However, while it is coarsely crystalline the cleavage angles can effortlessly be found with a hand lens. Dolomite has a Mohs hardness of 3 1/2 to 4 and is every now and then found in rhombohedral crystals with curved faces. Dolomite produces a totally vulnerable response to bloodless, dilute hydrochloric acid; but, if the acid is warm or if the dolomite is powdered, a much more potent acid reaction will be determined. (Powdered dolomite can easily be produced through scratching it on a streak plate.
Uses of Dolomite
Dolomite as a mineral has very few makes use of. However, dolostone has an vast number of uses as it happens in deposits which might be big sufficient to mine.
The maximum not unusual use for dolostone is within the production enterprise. It is crushed and sized to be used as a road base fabric, an aggregate in concrete and asphalt, railroad ballast, rip-rap, or fill. It is likewise calcined in the manufacturing of cement and reduce into blocks of particular size referred to as "size stone."
Dolomite's reaction with acid also makes it useful. It is used for acid neutralization in the chemical enterprise, in move restoration projects, and as a soil conditioner.
Dolomite is used as a supply of magnesia (MgO), a feed additive for farm animals, a sintering agent and flux in metal processing, and as an component within the production of glass, bricks, and ceramics.
Dolomite serves as the host rock for many lead, zinc, and copper deposits. These deposits shape while warm, acidic hydrothermal answers pass upward from depth thru a fracture gadget that encounters a dolomitic rock unit. These answers react with the dolomite, which reasons a drop in pH that triggers the precipitation of metals from answer.
Dolomite additionally serves as an oil and fuel reservoir rock. During the conversion of calcite to dolomite, a volume discount happens. This can produce pore spaces inside the rock that may be packed with oil or natural gasoline that migrate in as they're released from other rock devices. This makes the dolomite a reservoir rock and a target of oil and gas drilling.
