5 Formation

5.1 Formation

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

More about Anthracite and Granulite

Here you can know more about Anthracite and Granulite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anthracite and Granulite consists of mineral content and compound content. The mineral content of Anthracite includes Calcite, Clay, Clay Minerals and mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Anthracite vs Granulite, the texture, color and appearance plays an important role in determining the type of rock. Anthracite is available in black, brown, dark brown, grey, light to dark grey colors whereas, Granulite is available in black, brown colors. Appearance of Anthracite is Veined or Pebbled and that of Granulite is Veined or Pebbled. Properties of rock is another aspect for Anthracite vs Granulite. The hardness of Anthracite is 1-1.5 and that of Granulite is 6-7. The types of Anthracite are Semi-anthracite and Meta-anthracite whereas types of Granulite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Anthracite is black while that of Granulite is white. The specific heat capacity of Anthracite is 1.32 kJ/Kg K and that of Granulite is 0.14 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Anthracite is heat resistant, water resistant whereas Granulite is heat resistant, wear resistant.
