Archaeological Significance
Formation
Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.
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 Anthracite and Larvikite
Here you can know more about Anthracite and Larvikite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anthracite and Larvikite consists of mineral content and compound content. The mineral content of Anthracite includes Calcite, Clay, Clay Minerals 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 Metamorphic Rocks. When we have to compare Anthracite vs Larvikite, the texture, color and appearance plays an important role in determining the type of rock. Anthracite is available in black, brown, dark brown, grey, light to dark grey colors whereas, Larvikite is available in black, brown, light to dark grey, white colors. Appearance of Anthracite is Veined or Pebbled and that of Larvikite is Shiny. Properties of rock is another aspect for Anthracite vs Larvikite. The hardness of Anthracite is 1-1.5 and that of Larvikite is 6-7. The types of Anthracite are Semi-anthracite and Meta-anthracite 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 Anthracite is black while that of Larvikite is white. The specific heat capacity of Anthracite is 1.32 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.Anthracite is heat resistant, water resistant whereas Larvikite is heat resistant, impact resistant, pressure resistant.
