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.
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.

More about Larvikite and Anthracite
Here you can know more about Larvikite and Anthracite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Larvikite and Anthracite 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 Anthracite includes Calcite, Clay, Clay Minerals. You can also check out the list of all Igneous Rocks. When we have to compare Larvikite vs Anthracite, 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, Anthracite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Larvikite is Shiny and that of Anthracite is Veined or Pebbled. Properties of rock is another aspect for Larvikite vs Anthracite. The hardness of Larvikite is 6-7 and that of Anthracite is 1-1.5. The types of Larvikite are Quartz Monzonite, Syenite and Diorite whereas types of Anthracite are Semi-anthracite and Meta-anthracite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Larvikite is white while that of Anthracite is black. The specific heat capacity of Larvikite is 0.92 kJ/Kg K and that of Anthracite is 1.32 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 Anthracite is heat resistant, water resistant.
