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.
Coal formation takes place due to accumulation of plant debris in a swamp environment. The Coal formation process continues, as peat turns into lignite brown or black coal at increasing heat and pressure.

Larvikite vs Lignite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Larvikite vs Lignite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Larvikite and Properties of Lignite. Learn more about Larvikite vs Lignite in the next section. The interior uses of Larvikite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Lignite include Not yet used. Due to some exceptional properties of Larvikite and Lignite, they have various applications in construction industry. The uses of Larvikite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate and that of Lignite include For road aggregate, Steel production.
More about Larvikite and Lignite
Here you can know more about Larvikite and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Larvikite and Lignite 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 Lignite is not available. You can also check out the list of all Igneous Rocks. When we have to compare Larvikite vs Lignite, 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, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Larvikite is Shiny and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Larvikite vs Lignite. The hardness of Larvikite is 6-7 and that of Lignite is 1. The types of Larvikite are Quartz Monzonite, Syenite and Diorite whereas types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite. 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 Lignite is black. The specific heat capacity of Larvikite is 0.92 kJ/Kg K and that of Lignite is 1.26 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 Lignite is heat resistant.
