Features
Easily splits into thin plates, It is One of the Oldest, Strongest and Hardest Rock
Helps in production of Heat and Electricity, Used as fossil fuel
Archaeological Significance
Formation
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 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.

More about Metapelite and Anthracite
Here you can know more about Metapelite and Anthracite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Metapelite and Anthracite consists of mineral content and compound content. The mineral content of Metapelite includes Albite, Chlorite, 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 Metapelite vs Anthracite, the texture, color and appearance plays an important role in determining the type of rock. Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors whereas, Anthracite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Metapelite is Banded and that of Anthracite is Veined or Pebbled. Properties of rock is another aspect for Metapelite vs Anthracite. The hardness of Metapelite is 5-6 and that of Anthracite is 1-1.5. The types of Metapelite are Metamorphic rock 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 Metapelite is while that of Anthracite is black. The specific heat capacity of Metapelite is 0.72 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.Metapelite is heat resistant, impact resistant, pressure resistant whereas Anthracite is heat resistant, water resistant.
