Archaeological Significance
Formation
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.
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 Dolomite and Larvikite
Here you can know more about Dolomite and Larvikite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dolomite and Larvikite consists of mineral content and compound content. The mineral content of Dolomite includes Clay Minerals, Pyrite, Quartz, Sulfides 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 Dolomite vs Larvikite, the texture, color and appearance plays an important role in determining the type of rock. Dolomite is available in black, brown, green, grey, pink, white colors whereas, Larvikite is available in black, brown, light to dark grey, white colors. Appearance of Dolomite is Glassy or Pearly and that of Larvikite is Shiny. Properties of rock is another aspect for Dolomite vs Larvikite. The hardness of Dolomite is 3.5-4 and that of Larvikite is 6-7. The types of Dolomite are Boninite and Jasperoid 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 Dolomite and Larvikite is white. The specific heat capacity of Dolomite is 0.92 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.Dolomite is heat resistant, pressure resistant, wear resistant whereas Larvikite is heat resistant, impact resistant, pressure resistant.
