Definition
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight
Teschenite is coarse- to fine-grained, dark-coloured intrusive igneous rock that usually occurs in sills, dikes and irregular masses and is always altered to some extent

Formation
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.
Teschenite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Dolomite vs Teschenite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Dolomite vs Teschenite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dolomite and Properties of Teschenite. Learn more about Dolomite vs Teschenite in the next section. The interior uses of Dolomite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Teschenite include Countertops, Decorative aggregates, Entryways, Homes and Interior decoration. Due to some exceptional properties of Dolomite and Teschenite, they have various applications in construction industry. The uses of Dolomite in construction industry include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics, Serves as an oil and gas reservoir rock and that of Teschenite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Dolomite and Teschenite
Here you can know more about Dolomite and Teschenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dolomite and Teschenite consists of mineral content and compound content. The mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides and mineral content of Teschenite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Dolomite vs Teschenite, the texture, color and appearance plays an important role in determining the type of rock. Dolomite is available in black, brown, colourless, green, grey, pink, white colors whereas, Teschenite is available in dark grey to black colors. Appearance of Dolomite is Glassy or Pearly and that of Teschenite is Veined and Shiny. Properties of rock is another aspect for Dolomite vs Teschenite. The hardness of Dolomite is 3.5-4 and that of Teschenite is 7. The types of Dolomite are Boninite and Jasperoid whereas types of Teschenite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dolomite is white while that of Teschenite is black. The specific heat capacity of Dolomite is 0.92 kJ/Kg K and that of Teschenite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Dolomite is heat resistant, pressure resistant, wear resistant whereas Teschenite is impact resistant, pressure resistant, wear resistant.
