Definition
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
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
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.
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 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. Troctolite vs Serpentinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Troctolite and Properties of Serpentinite. Learn more about Troctolite vs Serpentinite in the next section. The interior uses of Troctolite include Bathrooms, Countertops, Decorative aggregates, Entryways, Flooring, Homes, Interior decoration and Kitchens whereas the interior uses of Serpentinite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Troctolite and Serpentinite, they have various applications in construction industry. The uses of Troctolite 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 Troctolite and Serpentinite
Here you can know more about Troctolite and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Troctolite and Serpentinite consists of mineral content and compound content. The mineral content of Troctolite 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 Troctolite vs Serpentinite, the texture, color and appearance plays an important role in determining the type of rock. Troctolite is available in dark grey to black colors whereas, Serpentinite is available in black, brown, colourless, green, grey, white colors. Appearance of Troctolite is Veined and Shiny and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Troctolite vs Serpentinite. The hardness of Troctolite is 7 and that of Serpentinite is 3-5. The types of Troctolite 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 Troctolite is black while that of Serpentinite is white, greenish white or grey. The specific heat capacity of Troctolite 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.Troctolite is impact resistant, pressure resistant, wear resistant whereas Serpentinite is heat resistant.
