About Dolomite or Hard Marble

GAIA Stone Gallery / About Dolomite or Hard Marble


Dolomite, also known as "dolostone rocks" and "dolomite rocks", is a sedimentary rock composed mainly of mineral dolomite, CaMg (CO3)2. Dolomite is present in sedimentary basins around the world. It is thought to have been caused by a postdepositional change of limestone mud and limestone by groundwater rich in magnesium.

Dolomite is very similar to mineral calcite. Calcite is composed of calcium carbonate (CaCO3), while dolomite is calcium magnesium carbonate (CaMg (CO3) 2). These two minerals are one of the most common couples that challenge the recognition of minerals in the field or in the classroom. Dolomite, like most natural stones, is porous and must be closed to prevent staining.

Dolomites are rarely found in modern sedimentary environments, but dolomites are very common in rock. They can be geographically extensive and thick from several hundred to thousands of meters. Most of the dolomite-rich rocks are originally stored as post-epitomized calcium carbonate sludge by pores containing magnesium-rich water to form a dolomite.

Physical properties of dolomite

Dolomite has three perfect cutting directions. This may not be visible when the dolomite is fine grained. However, when it is crystalline, the angle of excision can easily be observed with a manual lens. Dolomite has a Mohs hardness of 3 1/2 to 4 and is sometimes found in curved-faced romboedric crystals. Dolomite produces a very weak reaction to dilute and cold hydrochloric acid; however, if the acid is hot or if it is a dolomite powder, a much stronger acidic reaction will be observed. (Dolomite powder can easily be produced by scraping the scratch pad).

Uses of dolomite

Dolomites and limestone are used in the same way. They are crushed and used as aggregate in construction projects. They are kiln-fired in the manufacture of cement. They are cut into blocks and plates to serve as dimensional stone. Calcined for the production of lime. In some of these applications, dolomite is preferred. Its higher hardness makes it the ultimate building material. Its lower solubility makes it more resistant to the acid content of rain and soil.

The reaction of dolomite with an acid is also useful. It is used to neutralize acids in the chemical industry, in watercourse restoration projects and to improve the soil.

Dolomite is used as a source of magnesium oxide (MgO), a feed additive for cattle, a sintering agent and a metal treatment agent, and as an ingredient in the production of glass, brick and ceramics.

Dolomite is used as the main rock for many lead, zinc and copper deposits. These deposits occur when hot and acidic hydrothermal solutions move from depth through a fracture system satisfying the unit of dolomitic rock. These solutions react with dolomite, resulting in a decrease in the pH value, resulting in the precipitation of the metals in the solution.

Dolomite also serves as a reservoir of rocks for oil and gas. When converting calcite to dolomite, the volume decreases. This can create a breeding ground in a rock that can be filled with oil or natural gas that migrates as it is released from other rock units. This makes dolomite a bed of rock and a drill for oil and gas drilling.
