Formation
Mugearite forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.
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.

Mugearite vs Larvikite 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. Mugearite vs Larvikite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mugearite and Properties of Larvikite. Learn more about Mugearite vs Larvikite in the next section. The interior uses of Mugearite include Floor tiles, Flooring, Homes and Hotels whereas the interior uses of Larvikite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Mugearite and Larvikite, they have various applications in construction industry. The uses of Mugearite in construction industry include As dimension stone, Cobblestones, Rail track ballast, Roadstone and that of Larvikite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate.
More about Mugearite and Larvikite
Here you can know more about Mugearite and Larvikite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mugearite and Larvikite consists of mineral content and compound content. The mineral content of Mugearite includes Olivine, Plagioclase, Pyroxene 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 Mugearite vs Larvikite, the texture, color and appearance plays an important role in determining the type of rock. Mugearite is available in black, brown, light to dark grey colors whereas, Larvikite is available in black, brown, light to dark grey, white colors. Appearance of Mugearite is Dull and Soft and that of Larvikite is Shiny. Properties of rock is another aspect for Mugearite vs Larvikite. The hardness of Mugearite is 6 and that of Larvikite is 6-7. The types of Mugearite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite 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 Mugearite is white to grey while that of Larvikite is white. The specific heat capacity of Mugearite 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.Mugearite is heat resistant, pressure resistant, wear resistant whereas Larvikite is heat resistant, impact resistant, pressure resistant.
