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.
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

More about Larvikite and Basanite
Here you can know more about Larvikite and Basanite . The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Larvikite and Basanite 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 Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase. You can also check out the list of all Igneous Rocks. When we have to compare Larvikite vs Basanite , 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, Basanite is available in black, brown, green, grey, red, white colors. Appearance of Larvikite is Shiny and that of Basanite is Glassy or Pearly. Properties of rock is another aspect for Larvikite vs Basanite . The hardness of Larvikite is 6-7 and that of Basanite is 7. The types of Larvikite are Quartz Monzonite, Syenite and Diorite whereas types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Larvikite and Basanite is white. The specific heat capacity of Larvikite is 0.92 kJ/Kg K and that of Basanite is 0.74 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 Basanite is heat resistant, impact resistant, pressure resistant, wear resistant.
