Definition
Larvikite is an igneous rock and a variety of monzonite, notable for the presence of thumbnail-sized crystals of feldspar
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
Larvikite 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.

Larvikite 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. Larvikite vs Serpentinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Larvikite and Properties of Serpentinite. Learn more about Larvikite vs Serpentinite in the next section. The interior uses of Larvikite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Serpentinite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Larvikite and Serpentinite, they have various applications in construction industry. The uses of Larvikite in construction industry include As dimension stone, 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 Larvikite and Serpentinite
Here you can know more about Larvikite and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Larvikite and Serpentinite consists of mineral content and compound content. The mineral content of Larvikite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon 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 Larvikite vs Serpentinite, the texture, color and appearance plays an important role in determining the type of rock. Larvikite is available in black, brown, light to dark grey, white colors whereas, Serpentinite is available in black, brown, green, grey, white colors. Appearance of Larvikite is Shiny and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Larvikite vs Serpentinite. The hardness of Larvikite is 6-7 and that of Serpentinite is 3-5. The types of Larvikite are Quartz Monzonite, Syenite and Diorite 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 Larvikite is white while that of Serpentinite is white, greenish white or grey. The specific heat capacity of Larvikite is 0.92 kJ/Kg K 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.Larvikite is heat resistant, impact resistant, pressure resistant whereas Serpentinite is heat resistant.
