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
  
A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.

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.
  
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Teschenite vs Serpentinite 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 Serpentinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Teschenite and Properties of Serpentinite. Learn more about Teschenite vs Serpentinite in the next section. The interior uses of Teschenite include Countertops, Decorative aggregates, Entryways, Homes and Interior decoration whereas the interior uses of Serpentinite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Teschenite and Serpentinite, 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 Serpentinite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.
More about Teschenite and Serpentinite
Here you can know more about Teschenite and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Teschenite and Serpentinite consists of mineral content and compound content. The mineral content of Teschenite includes Augite, Olivine, Plagioclase, Pyroxene and mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Teschenite vs Serpentinite, 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, Serpentinite is available in black, brown, colourless, green, grey, white colors. Appearance of Teschenite is Veined and Shiny and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Teschenite vs Serpentinite. The hardness of Teschenite is 7 and that of Serpentinite is 3-5. The types of Teschenite are Not Available whereas types of Serpentinite are Jadeitite. 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 Serpentinite is white, greenish white or grey. The specific heat capacity of Teschenite is Not Available and that of Serpentinite is 0.95 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 Serpentinite is heat resistant.
