5 Formation
5.1 Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Pseudotachylite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
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.

Pseudotachylite vs Larvikite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Pseudotachylite and Larvikite Reserves. Very fine grained fault rock which is composed of glassy matrix that often contains inclusions of wall-rock fragments.. Larvikite is an igneous rock and a variety of monzonite, notable for the presence of thumbnail-sized crystals of feldspar. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Pseudotachylite vs Larvikite information and Pseudotachylite vs Larvikite characteristics in the upcoming sections.

Pseudotachylite vs Larvikite Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others.

More about Pseudotachylite and Larvikite

Here you can know more about Pseudotachylite and Larvikite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pseudotachylite and Larvikite consists of mineral content and compound content. The mineral content of Pseudotachylite includes Iron Oxides, Pyroxene, Quartz, Stishovite, Sulfides 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 Metamorphic Rocks. When we have to compare Pseudotachylite vs Larvikite, the texture, color and appearance plays an important role in determining the type of rock. Pseudotachylite is available in black, brown, colourless, green, grey, pink, white colors whereas, Larvikite is available in black, brown, light to dark grey, white colors. Appearance of Pseudotachylite is Dull and Soft and that of Larvikite is Shiny. Properties of rock is another aspect for Pseudotachylite vs Larvikite. The hardness of Pseudotachylite is 7 and that of Larvikite is 6-7. The types of Pseudotachylite are Not Available 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 Pseudotachylite is light to dark brown while that of Larvikite is white. The specific heat capacity of Pseudotachylite is 0.92 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.Pseudotachylite is heat resistant whereas Larvikite is heat resistant, impact resistant, pressure resistant.
