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

More about Basanite and Larvikite
Here you can know more about Basanite and Larvikite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Basanite and Larvikite consists of mineral content and compound content. The mineral content of Basanite includes Augite, Feldspar, Ilmenite, Olivine, Plagioclase 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 Basanite vs Larvikite, the texture, color and appearance plays an important role in determining the type of rock. Basanite is available in black, brown, green, grey, red, white colors whereas, Larvikite is available in black, brown, light to dark grey, white colors. Appearance of Basanite is Glassy or Pearly and that of Larvikite is Shiny. Properties of rock is another aspect for Basanite vs Larvikite. The hardness of Basanite is 7 and that of Larvikite is 6-7. The types of Basanite are Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite 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 Basanite and Larvikite is white. The specific heat capacity of Basanite is 0.74 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.Basanite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Larvikite is heat resistant, impact resistant, pressure resistant.
