5 Formation

5.1 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.

When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes tonalite with quartz as major mineral.

Granulite vs Tonalite 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 Granulite and Tonalite Reserves. Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.. Tonalite is a coarse-grained plutonic rock consisting mainly of sodic plagioclase, quartz, and hornblende or other mafic minerals with phaneritic texture. 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 Granulite vs Tonalite information and Granulite vs Tonalite characteristics in the upcoming sections.

More about Granulite and Tonalite

Here you can know more about Granulite and Tonalite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Tonalite 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 Tonalite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Manganese Oxides, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Tonalite, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Tonalite is available in black, brown, light to dark grey, white colors. Appearance of Granulite is Veined or Pebbled and that of Tonalite is Banded and Foilated. Properties of rock is another aspect for Granulite vs Tonalite. Hardness of Granulite and Tonalite is 6-7. The types of Granulite are Not Available whereas types of Tonalite are Dacite. 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 Tonalite is bluish black. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Tonalite 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.Granulite is heat resistant, wear resistant whereas Tonalite is heat resistant, pressure resistant, water resistant.
