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.
Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.

Larvikite vs Peridotite 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 Peridotite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Larvikite and Properties of Peridotite. Learn more about Larvikite vs Peridotite in the next section. The interior uses of Larvikite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Peridotite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Larvikite and Peridotite, 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 Peridotite include As dimension stone, Cobblestones.
More about Larvikite and Peridotite
Here you can know more about Larvikite and Peridotite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Larvikite and Peridotite 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 Peridotite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all . When we have to compare Larvikite vs Peridotite, 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, Peridotite is available in dark greenish - grey colors. Appearance of Larvikite is Shiny and that of Peridotite is Rough and Shiny. Properties of rock is another aspect for Larvikite vs Peridotite. The hardness of Larvikite is 6-7 and that of Peridotite is 5.5-6. The types of Larvikite are Quartz Monzonite, Syenite and Diorite whereas types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Larvikite and Peridotite is white. The specific heat capacity of Larvikite is 0.92 kJ/Kg K and that of Peridotite is 1.26 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 Peridotite is heat resistant, pressure resistant, wear resistant.
