Definition
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'.
Troctolite is a mafic intrusive rock type. It consists essentially of major but variable amounts of olivine and calcic plagioclase along with minor pyroxene. It is an olivine-rich anorthosite, or a pyroxene-depleted relative of gabbro

Formation
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.
Troctolite 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.

Serpentinite vs Troctolite 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. Serpentinite vs Troctolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Serpentinite and Properties of Troctolite. Learn more about Serpentinite vs Troctolite in the next section. The interior uses of Serpentinite include Decorative aggregates and Interior decoration whereas the interior uses of Troctolite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Serpentinite and Troctolite, they have various applications in construction industry. The uses of Serpentinite in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement and that of Troctolite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Serpentinite and Troctolite
Here you can know more about Serpentinite and Troctolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Troctolite consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Troctolite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Troctolite, the texture, color and appearance plays an important role in determining the type of rock. Serpentinite is available in black, brown, green, grey, white colors whereas, Troctolite is available in dark grey to black colors. Appearance of Serpentinite is Rough and Dull and that of Troctolite is Veined and Shiny. Properties of rock is another aspect for Serpentinite vs Troctolite. The hardness of Serpentinite is 3-5 and that of Troctolite is 7. The types of Serpentinite are Jadeitite whereas types of Troctolite are Ultramafic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Serpentinite is white, greenish white or grey while that of Troctolite is black. The specific heat capacity of Serpentinite is 0.95 kJ/Kg K and that of Troctolite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Serpentinite is heat resistant whereas Troctolite is impact resistant, pressure resistant, wear resistant.
