Formation
Wehrlite 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.

Wehrlite 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. Wehrlite vs Larvikite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Wehrlite and Properties of Larvikite. Learn more about Wehrlite vs Larvikite in the next section. The interior uses of Wehrlite 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 Wehrlite and Larvikite, they have various applications in construction industry. The uses of Wehrlite 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 Wehrlite and Larvikite
Here you can know more about Wehrlite and Larvikite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Larvikite consists of mineral content and compound content. The mineral content of Wehrlite includes 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 Wehrlite vs Larvikite, the texture, color and appearance plays an important role in determining the type of rock. Wehrlite is available in dark greenish - grey, green colors whereas, Larvikite is available in black, brown, light to dark grey, white colors. Appearance of Wehrlite is Rough and Banded and that of Larvikite is Shiny. Properties of rock is another aspect for Wehrlite vs Larvikite. The hardness of Wehrlite is 5.5-6 and that of Larvikite is 6-7. The types of Wehrlite are Not Available 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 Wehrlite and Larvikite is white. The specific heat capacity of Wehrlite is 0.63 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.Wehrlite is heat resistant, impact resistant, pressure resistant whereas Larvikite is heat resistant, impact resistant, pressure resistant.
