Formation
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.
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 Andesite and Larvikite
Here you can know more about Andesite and Larvikite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Andesite and Larvikite consists of mineral content and compound content. The mineral content of Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon 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 Andesite vs Larvikite, the texture, color and appearance plays an important role in determining the type of rock. Andesite is available in bluish - grey, grey, pink, yellow colors whereas, Larvikite is available in black, brown, light to dark grey, white colors. Appearance of Andesite is Dull and Soft and that of Larvikite is Shiny. Properties of rock is another aspect for Andesite vs Larvikite. The hardness of Andesite is 7 and that of Larvikite is 6-7. The types of Andesite are Icelandite 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 Andesite and Larvikite is white. The specific heat capacity of Andesite is 2.39 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.Andesite is heat resistant, pressure resistant, wear resistant whereas Larvikite is heat resistant, impact resistant, pressure resistant.
