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.
Pumice rock forms when the magma cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.

The interior uses of Larvikite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Pumice include Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Larvikite and Pumice, 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 Pumice include As dimension stone, Cement manufacture, For road aggregate, In landscaping and horticulture, Making natural cement, Production of lightweight concrete blocks.
More about Larvikite and Pumice
Here you can know more about Larvikite and Pumice. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Larvikite and Pumice 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 Pumice includes Aluminum Oxides, Calcite, Carbonate, Iron Oxides, Silica. You can also check out the list of all . When we have to compare Larvikite vs Pumice, 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, Pumice is available in beige, colourless, grey, light green, light grey, pink, white, yellow- grey colors. Appearance of Larvikite is Shiny and that of Pumice is Vesicular. Properties of rock is another aspect for Larvikite vs Pumice. The hardness of Larvikite is 6-7 and that of Pumice is 6. The types of Larvikite are Quartz Monzonite, Syenite and Diorite whereas types of Pumice are Scoria. 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 Pumice is white, greenish white or grey. The specific heat capacity of Larvikite is 0.92 kJ/Kg K and that of Pumice is 0.87 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 Pumice is impact resistant, pressure resistant.
