Formation
Pyrolite 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.
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.

Pyrolite vs Larvikite 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. Pyrolite vs Larvikite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Pyrolite and Properties of Larvikite. Learn more about Pyrolite vs Larvikite in the next section. The interior uses of Pyrolite include Decorative aggregates and Interior decoration whereas the interior uses of Larvikite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Pyrolite and Larvikite, they have various applications in construction industry. The uses of Pyrolite in construction industry include As dimension stone, Cobblestones and that of Larvikite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate.
More about Pyrolite and Larvikite
Here you can know more about Pyrolite and Larvikite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pyrolite and Larvikite consists of mineral content and compound content. The mineral content of Pyrolite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene and mineral content of Larvikite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Pyrolite vs Larvikite, the texture, color and appearance plays an important role in determining the type of rock. Pyrolite is available in dark greenish - grey colors whereas, Larvikite is available in black, brown, light to dark grey, white colors. Appearance of Pyrolite is Rough and Shiny and that of Larvikite is Shiny. Properties of rock is another aspect for Pyrolite vs Larvikite. The hardness of Pyrolite is 5.5-6 and that of Larvikite is 6-7. The types of Pyrolite are Dunite, Wehrlite, Harzburgite, Lherzolite whereas types of Larvikite are Quartz Monzonite, Syenite and Diorite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Pyrolite and Larvikite is white. The specific heat capacity of Pyrolite is 1.25 kJ/Kg K and that of Larvikite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Pyrolite is heat resistant, pressure resistant, wear resistant whereas Larvikite is heat resistant, impact resistant, pressure resistant.
