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.
  
Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.

Larvikite vs Diabase 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 Diabase characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Larvikite and Properties of Diabase. Learn more about Larvikite vs Diabase in the next section. The interior uses of Larvikite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Diabase include Countertops, Decorative aggregates, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Larvikite and Diabase, 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 Diabase include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Larvikite and Diabase
Here you can know more about Larvikite and Diabase. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Larvikite and Diabase 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 Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine. You can also check out the list of all Igneous Rocks. When we have to compare Larvikite vs Diabase, 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, Diabase is available in dark grey to black colors. Appearance of Larvikite is Shiny and that of Diabase is Vesicular. Properties of rock is another aspect for Larvikite vs Diabase. The hardness of Larvikite is 6-7 and that of Diabase is 7. The types of Larvikite are Quartz Monzonite, Syenite and Diorite whereas types of Diabase are Not Available. 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 Diabase is black. The specific heat capacity of Larvikite is 0.92 kJ/Kg K and that of Diabase is Not Available. 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 Diabase is heat resistant, impact resistant, pressure resistant, wear resistant.
