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.

Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.

Granulite vs Anthracite 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 Anthracite Reserves. Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.. Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster. 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 Anthracite information and Granulite vs Anthracite characteristics in the upcoming sections.

More about Granulite and Anthracite

Here you can know more about Granulite and Anthracite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Anthracite 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 Anthracite includes Calcite, Clay, Clay Minerals. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Anthracite, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Anthracite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Granulite is Veined or Pebbled and that of Anthracite is Veined or Pebbled. Properties of rock is another aspect for Granulite vs Anthracite. The hardness of Granulite is 6-7 and that of Anthracite is 1-1.5. The types of Granulite are Not Available whereas types of Anthracite are Semi-anthracite and Meta-anthracite. 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 Anthracite is black. The specific heat capacity of Granulite is 0.14 kJ/Kg K and that of Anthracite is 1.32 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 Anthracite is heat resistant, water resistant.
