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.

Gritstone is a type of sedimentary rock which was formed on the floors of wide river deltas where the grit deposits were laid down, with every tide or flood dumping another layer of sediment.

Granulite vs Gritstone 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 Gritstone Reserves. Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.. Gritstone or grit is a hard, coarse-grained, siliceous sandstone. 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 Gritstone information and Granulite vs Gritstone characteristics in the upcoming sections.

More about Granulite and Gritstone

Here you can know more about Granulite and Gritstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Gritstone 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 Gritstone includes Calcite, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Gritstone, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Gritstone is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. Appearance of Granulite is Veined or Pebbled and that of Gritstone is Layered and Foliated. Properties of rock is another aspect for Granulite vs Gritstone. Hardness of Granulite and Gritstone is 6-7. The types of Granulite are Not Available whereas types of Gritstone 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 Gritstone is white. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Gritstone 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 Gritstone is heat resistant, impact resistant, pressure resistant.
