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.
Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.

More about Larvikite and Chalk
Here you can know more about Larvikite and Chalk. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Larvikite and Chalk 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 Chalk includes Calcite, Clay, Clay Minerals, Quartz, Sand. You can also check out the list of all Igneous Rocks. When we have to compare Larvikite vs Chalk, 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, Chalk is available in grey, white, yellow colors. Appearance of Larvikite is Shiny and that of Chalk is Soft. Properties of rock is another aspect for Larvikite vs Chalk. The hardness of Larvikite is 6-7 and that of Chalk is 1. The types of Larvikite are Quartz Monzonite, Syenite and Diorite whereas types of Chalk are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Larvikite and Chalk is white. The specific heat capacity of Larvikite is 0.92 kJ/Kg K and that of Chalk is 0.90 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 Chalk is heat resistant.
