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

Anthracite vs Quartzite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Anthracite vs Quartzite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anthracite and Properties of Quartzite. Learn more about Anthracite vs Quartzite in the next section. The interior uses of Anthracite include Not yet used whereas the interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes. Due to some exceptional properties of Anthracite and Quartzite, they have various applications in construction industry. The uses of Anthracite in construction industry include Cement manufacture, For road aggregate, Making natural cement, Steel production and that of Quartzite include Arrowheads, As dimension stone, Cement manufacture, Construction aggregate, Cutting tool, For road aggregate, Making natural cement, Production of glass and ceramics, Rail track ballast, Roadstone.
More about Anthracite and Quartzite
Here you can know more about Anthracite and Quartzite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anthracite and Quartzite consists of mineral content and compound content. The mineral content of Anthracite includes Calcite, Clay, Clay Minerals and mineral content of Quartzite includes Chlorite, Epidote, Hematite, Kyanite, Magnetite, Muscovite or Illite, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Anthracite vs Quartzite, 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, Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. Appearance of Anthracite is Veined or Pebbled and that of Quartzite is Lustrous. Properties of rock is another aspect for Anthracite vs Quartzite. The hardness of Anthracite is 1-1.5 and that of Quartzite is 6-7. The types of Anthracite are Semi-anthracite and Meta-anthracite whereas types of Quartzite 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 Quartzite is white. The specific heat capacity of Anthracite is 1.32 kJ/Kg K and that of Quartzite is 0.75 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 Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant.
