Archaeological Significance
Formation
Diorite is a coarse-grained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reach the Earth’s surface and cools down in the Earth’s crust.
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 Diorite and Larvikite
Here you can know more about Diorite and Larvikite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diorite and Larvikite consists of mineral content and compound content. The mineral content of Diorite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, 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 Diorite vs Larvikite, the texture, color and appearance plays an important role in determining the type of rock. Diorite is available in black, brown, light to dark grey, white colors whereas, Larvikite is available in black, brown, light to dark grey, white colors. Appearance of Diorite is Shiny and that of Larvikite is Shiny. Properties of rock is another aspect for Diorite vs Larvikite. Hardness of Diorite and Larvikite is 6-7. The types of Diorite are Plagioclase Diorite and Quartz Diorite 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 Diorite is bluish black while that of Larvikite is white. The specific heat capacity of Diorite is 0.84 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.Diorite is heat resistant, pressure resistant, wear resistant whereas Larvikite is heat resistant, impact resistant, pressure resistant.
