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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Anthracite vs Metapelite 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 Metapelite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anthracite and Properties of Metapelite. Learn more about Anthracite vs Metapelite in the next section. The interior uses of Anthracite include Not yet used whereas the interior uses of Metapelite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Anthracite and Metapelite, 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 Metapelite include Cement manufacture, Construction aggregate, For road aggregate.
More about Anthracite and Metapelite
Here you can know more about Anthracite and Metapelite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anthracite and Metapelite consists of mineral content and compound content. The mineral content of Anthracite includes Calcite, Clay, Clay Minerals and mineral content of Metapelite includes Albite, Chlorite, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Anthracite vs Metapelite, 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, Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors. Appearance of Anthracite is Veined or Pebbled and that of Metapelite is Banded. Properties of rock is another aspect for Anthracite vs Metapelite. The hardness of Anthracite is 1-1.5 and that of Metapelite is 5-6. The types of Anthracite are Semi-anthracite and Meta-anthracite whereas types of Metapelite 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 Metapelite is unknown. The specific heat capacity of Anthracite is 1.32 kJ/Kg K and that of Metapelite is 0.72 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 Metapelite is heat resistant, impact resistant, pressure resistant.
