Sedimentary carbonate rocks: dolomite
白云岩（dolomite）
One kind of sedimentary carbonate rocks. Mainly composed of dolomite, often mixed with quartz, feldspar, calcite and clay minerals. Pale, brittle, hardness is small, easy to draw with iron scratches. Case of dilute hydrochloric acid slowly bubbling or blistering, appearance and very similar to limestone. By cause can be divided into primary dolomite, diagenetic dolomite and epigenetic dolomite; according to the structure can be divided into crystalline dolomite, the residual particles of alienation dolomite, detrital dolomite, microcrystalline dolomite and so on. High magnesium dolomite, weathering to form a white powder. Tenacity than limestone. Can be used in the metallurgical industry flux and refractories, in the chemical industry can produce calcium magnesium phosphate, granular fertilizer. In addition, as ceramics, glass ingredients and building stone Mainly by dolomite (50%) composed of rock. Is a carbonate rock, like limestone appearance to foam slightly different from the limestone and acid. Can be used as refractories and other industrial raw materials. Common names in the field are the following: ① micritic dolomite: from less than 0.005 mm, composed of micritic dolomite, uniform structure, with a microscopic layer of management, biological debris rarely, sometimes visible ostracodes, mostly native dolomite. ② micro - fine grain dolomite: crystal sizes, crystal quite good, looks just like sugar, sugar, dolomite can call it the wild, often by other types of dolomite recrystallization from. ③ algal dolomite: The algal limestone similar to that of dolomite formed by the algae fossils, China Proterozoic and Sinian dolomite strata are mostly of this type, it may be native dolomite type. ④ biological bioclastic dolomite and dolomite: the fossil remnants of them visible, and more from the bioclastic limestone formed by the dolomitization metasomatism. ⑤ within the clastic dolostone: According to one of the pieces are size of the chip can be divided into gravel, sand dust, Fenxie dolomite. They are often found in the general form of laminated layers of clouds. Formed in the shallow intertidal zone over the upper or the environment, the debris that is formed by the shock waves or currents. ⑥ oolitic dolomite: This is a class of secondary dolomite, from oolitic limestone formed by dolomitization. Because of its porosity, the larger, often ideal for oil or groundwater storage layer. To the causes in terms of dolomite. Conditions of its formation, the dolomite can be divided into three categories: Native dolomite: in-situ deposition of dolomite, dry and hot weather in the (28 ℃ ~ 35 ℃) formed under evaporation. High salinity and shallow (0 to 3 m deep tidal belt), PH value is higher than the 8.3 of the salt form of the lagoon or bay can also be formed in salt lake in the land, and frequently with a salt layers. Diagenetic dolomite: the process in the precipitation of calcium carbonate, dolomite account was made, usually distributed discontinuous lenses in the limestone layer was body-like or plaque, and sometimes into the laminar distribution, extending a certain distance. Secondary dolomite: also known as epigenetic dolomite, distribution limitations, common in the fault zone.

baiyunyan Dolomite dolomite Composed mainly of carbonate dolomite. Composition theory of dolomite, the original dolomite, freshwater dolomite and salt dolomite. ① theory of dolomite is Ca2 +, Mg2 + cations as the 1:1 ordered structure of the carbonate minerals, the ancient strata of dolomite mostly this mineral. ② the original dolomite is Ca2 +: Mg2 +> 1 the structure of ordered weaker dolomite, the main output in the modern sediments. Its surface condition is stable, only heated to above 200 ℃ to remove the lattice of excess calcium to form a theory of dolomite. So, in normal temperature and pressure of the original dolomite is not accessible to the theory of dolomite transformation. ③ freshwater and low salinity groundwater in the lack of ion competition and crystallization of the slow formation of the ordered structure of dolomite. Such dolomite found in modern rivers, freshwater lakes, cave deposits and soil crust Zhong. ④ brine dolomite is high brine environment Mg2 + at high concentrations, mold quickly formed in the Ca2 + / Mg2 + types according to form is divided into the following three categories. ① syngenetic dolomite, sedimentary diagenesis early or penecontemporaneous the formation of micritic dolomite composed of dolomite, fabric uniform and compact size is usually less than 0.03 mm, layer stability, and development of fine bedding, little fossil-bearing, non-dolomite account calcite signs. ② diagenetic dolomite, is the process of diagenesis of calcium carbonate by magnesium ions account for the formation of rocks. Dolomite mostly fine grain structure, dolomite is about 0.1 ~ 0.01 mm granular irregular diamond-shaped crystal grains often has cloudy form, containing more calcium carbonate residual enclaves or a cloudy core structure, you can often see the dolomite account of calcium carbonate particles and biological shells traces of diagenetic dolomite usually layered, lenticular production, and limestone contact with boundary is not regular. ③ epigenetic dolomite (also known as secondary dolomite), are the consolidation of diagenesis of the limestone and then by magnesium ions account for the formation of dolomite. With obvious uneven account of the structure, dolomite particle thick, and large and small, developed euhedral rhombohedral and zonal structure. Rock porous, bedding is not obvious, only visible remnants of bedding structure and biological residual nuclei. Epigenetic Dolomite and the surrounding unaffected dolomitization of the limestone was mutated contact relationship. Origin of dolomite has been the cause of a problem in geology. Almost all synthetic dolomite proved that only higher than 200 ℃ temperature conditions can be synthesized and orderly theory of dolomite. 200 ~ 120 ℃ in the synthesis of mostly disordered between the original dolomite. Some people think that 60 years, with increasing temperature, increasing the reagent concentration, reaction speed reduction methods, you can control the degree of dolomite crystals and ordered. Modern dolomite deposition has been in the Caribbean, Andrew Island, Florida South Bay, southeast coast of Australia, the library □ Long Lake, south bank of Qatar, the Persian Gulf - Abu Dhabi, tidal and other places have found. Modern dolomite sediments in the original order is bad mainly dolomite, formed in the 0 to 3 meters in supratidal or intertidal and subtidal pH> 9 and above and below normal sea water salinity High 5 to 8 times the alkaline water. From the thermodynamic equilibrium theory, can not order from the ocean water, direct precipitation of dolomite, CaCO3 minerals therefore proposed as Mr., are accountable to the formation of Mg2 + in solution of dolomite dolomitization of the various theories, such as the role of percolation reflux, evaporation capillary action pump, adjusting and mixing dolomitization dolomitization and other theories. In addition, raised in freshwater and low salinity water due to lack of competition in the formation of dolomite and slow crystallization rate of ions to form the theory of ordered dolomite dolomite ─ ─ freshwater origin said. Great thickness of the layer needs further study the causes of dolomite. Dolomite as raw materials for refining magnesium and iron can be used as additives. (Meng of the)

The main purpose of dolomite
Dolomite is widely used in building materials, ceramics, welding, rubber, paper, plastics and other industries. Also in agriculture, environmental protection, energy, pharmaceutical and health care and other fields has also been applied. (1) in the metallurgical industry on the use of Dolomite in the metallurgical industry is mainly used as flux, refractories, refining of metal magnesium and magnesium compounds. Used as a flux dolomite as iron and steel of the flux, can play and acid slag, and improve the slag basicity, lower slag FeO of the activity, to reduce the slag on the lining of the erosion. Light burnt dolomite is mainly used in steel making, steel slag can improve mobility, as slagging agent use, not only extended the life of the converter to improve the mobility of the slag, and to improve the desulfurization, dephosphorization reaction, can also save a lot of fluorite. Currently China's production of 1t of steel need to consume 170kg dolomite. In iron are added to dolomite to dilute the slag, reducing the slag melting point, lower fuel consumption, improve iron quality. Used as a basic refractory dolomite refractories, mainly used for steel-making furnaces Martin, Thomas's back to the converter lining, also used as the basic open-hearth furnace bottom and slope materials and complement the process of smelting furnace materials. Quality in smelting iron and manganese alloy, silicon alloy, the dolomite often specific charge. Slagging in the steelmaking process while adding the right amount of light burned dolomite or dolomite, which is a new approach in recent years to replace part of the lime, thereby inhibiting the lining of the MgO dissolved in the slag. Dolomite may promote early accession of Java, the MgO saturated slag, slag viscosity to improve on the lining of a better adhesion, play a protective role in lining. (2) the use of the building materials industry (3) use in the chemical industry Dolomite is mainly used for production of magnesium sulfate, light magnesium carbonate and other chemicals. 30% sulfuric acid and dolomite by mixing, reaction, separation and concentration, the temperature rise under conditions of precipitation of calcium sulfate, magnesium sulfate solution obtained cooling and crystallization, that was magnesium sulfate (MgSO4 × 7H2O). Extracted from seawater Mg (OH) 2, when used as a precipitating agent calcined dolomite, the dolomite also recovered in the MgO, the increased production. To calcined dolomite, digestion, carbonation, filtration separation, was re-magnesium water, and then thermal decomposition filter, too light magnesium [xMgCO3 × yMg (OH) 2 × zH2O]. Decomposition of light magnesium oxide light magnesium carbonate, and use it to burn high purity magnesite. (4) use in agriculture Dolomite can be used as a neutralizer of soil acidity, and also the use of urea fertilizer caused a class of acidic, improve crop production. Dolomite is mainly used for neutralizing acidic soil, use can compensate for crop uptake of soil brought about the loss of calcium and magnesium, the application of dolomite can improve crop production 15-40%. Calcite and dolomite treated quality agricultural lime can be used as the rule of pesticides to prevent pests. (5) for use as fill Dolomite can be used for rubber, paper fillers. Quality of dolomite powder, titanium dioxide can be used for packing expensive substitutes, for a number of products, packing, can improve products, color, resistance to weathering capabilities, improved mechanical stability, reduce shrinkage and internal tension, reduce water and oil absorption capacity and the expansion of cracks, such products including adhesives, sealing plastics, paints, detergents and cosmetics.
