5 Formation

5.1 Formation

Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

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.

Quartzite 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 Quartzite and Anthracite Reserves. Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone. 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 Quartzite vs Anthracite information and Quartzite vs Anthracite characteristics in the upcoming sections.

More about Quartzite and Anthracite

Here you can know more about Quartzite and Anthracite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Quartzite and Anthracite consists of mineral content and compound content. The mineral content of Quartzite includes Chlorite, Epidote, Hematite, Kyanite, Magnetite, Muscovite or Illite, 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 Quartzite vs Anthracite, the texture, color and appearance plays an important role in determining the type of rock. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas, Anthracite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Quartzite is Lustrous and that of Anthracite is Veined or Pebbled. Properties of rock is another aspect for Quartzite vs Anthracite. The hardness of Quartzite is 6-7 and that of Anthracite is 1-1.5. The types of Quartzite 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 Quartzite is white while that of Anthracite is black. The specific heat capacity of Quartzite is 0.75 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.Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Anthracite is heat resistant, water resistant.
