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.

Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.

Granulite vs Chalk 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 Chalk Reserves. Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. 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.

More about Granulite and Chalk

Here you can know more about Granulite and Chalk. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Chalk 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 Chalk includes Calcite, Clay, Clay Minerals, Quartz, Sand. You can also check out the list of all . When we have to compare Granulite vs Chalk, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Chalk is available in grey, white, yellow colors. Appearance of Granulite is Veined or Pebbled and that of Chalk is Soft. Properties of rock is another aspect for Granulite vs Chalk. The hardness of Granulite is 6-7 and that of Chalk is 1. The types of Granulite are Not Available whereas types of Chalk 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 Chalk is white. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Chalk is 0.90 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 Chalk is heat resistant.
