Definition

Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.

Tachylite is a vitreous form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt

Formation

Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

Tachylite 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.

More about Granulite and Tachylite

Here you can know more about Granulite and Tachylite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Tachylite consists of mineral content and compound content. The mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz and mineral content of Tachylite includes Feldspar, Olivine. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Tachylite, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Tachylite is available in black, dark brown colors. Appearance of Granulite is Veined or Pebbled and that of Tachylite is Glassy. Properties of rock is another aspect for Granulite vs Tachylite. The hardness of Granulite is 6-7 and that of Tachylite is 5.5. The types of Granulite are Metamorphic rock whereas types of Tachylite are Volcanic glass. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granulite is white while that of Tachylite is vermilion. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Tachylite is 0.56 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Granulite is heat resistant, wear resistant whereas Tachylite is heat resistant, impact resistant, wear resistant.
