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.
Syenites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

Larvikite vs Syenite 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 Syenite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Larvikite and Properties of Syenite. Learn more about Larvikite vs Syenite in the next section. The interior uses of Larvikite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Syenite include Flooring, Homes, Hotels and Interior decoration. Due to some exceptional properties of Larvikite and Syenite, 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 Syenite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Larvikite and Syenite
Here you can know more about Larvikite and Syenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Larvikite and Syenite 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 Syenite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Larvikite vs Syenite, 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, Syenite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Larvikite is Shiny and that of Syenite is Banded and Foilated. Properties of rock is another aspect for Larvikite vs Syenite. The hardness of Larvikite is 6-7 and that of Syenite is 5.5-6. The types of Larvikite are Quartz Monzonite, Syenite and Diorite whereas types of Syenite are Shonkinite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Larvikite and Syenite is white. The specific heat capacity of Larvikite is 0.92 kJ/Kg K and that of Syenite 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.Larvikite is heat resistant, impact resistant, pressure resistant whereas Syenite is heat resistant, impact resistant, wear resistant.
