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.

Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.

Granulite vs Arkose 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 Arkose Reserves. Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.. Arkose is a sedimentary rock, specifically a type of sandstone containing at least 25% 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 Granulite vs Arkose information and Granulite vs Arkose characteristics in the upcoming sections.

More about Granulite and Arkose

Here you can know more about Granulite and Arkose. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Arkose 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 Arkose includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Arkose, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Arkose is available in reddish brown colors. Appearance of Granulite is Veined or Pebbled and that of Arkose is Rough and Dull. Properties of rock is another aspect for Granulite vs Arkose. Hardness of Granulite and Arkose is 6-7. The types of Granulite are Not Available whereas types of Arkose are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granulite and Arkose is white. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Arkose is Not Available. 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 Arkose is heat resistant, impact resistant, pressure resistant.
