Definition
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
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight
Origin

Etymology
From its occurrence near Teschen. now known as Cieszyn, Pol., Scotland
From French, from the name of Dolomieu (1750–1801), the French geologist who discovered the rock

Formation
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 rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

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