Formation
Diatomite rock formed from the skeletal remains of single celled plants called diatoms. When diatoms die, their skeletal remains sink to the bottom of lakes and oceans etc. hence forming diatomite deposit.
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 Diatomite and Larvikite
Here you can know more about Diatomite and Larvikite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diatomite and Larvikite consists of mineral content and compound content. The mineral content of Diatomite includes Calcite, Clay, Clay Minerals, Quartz, Sand 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 Sedimentary Rocks. When we have to compare Diatomite vs Larvikite, the texture, color and appearance plays an important role in determining the type of rock. Diatomite is available in grey, white, yellow colors whereas, Larvikite is available in black, brown, light to dark grey, white colors. Appearance of Diatomite is Soft and that of Larvikite is Shiny. Properties of rock is another aspect for Diatomite vs Larvikite. The hardness of Diatomite is 1 and that of Larvikite is 6-7. The types of Diatomite are Not Available 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 Diatomite and Larvikite is white. The specific heat capacity of Diatomite is 0.90 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.Diatomite is heat resistant whereas Larvikite is heat resistant, impact resistant, pressure resistant.
