Features
Helps in production of Heat and Electricity, Used as fossil fuel
Available in Lots of Colors and Patterns, It is One of the Oldest, Strongest and Hardest Rock
Archaeological Significance
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.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

More about Anthracite and Enderbite
Here you can know more about Anthracite and Enderbite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anthracite and Enderbite consists of mineral content and compound content. The mineral content of Anthracite includes Calcite, Clay, Clay Minerals and mineral content of Enderbite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Anthracite vs Enderbite, 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, Enderbite is available in black, grey, orange, pink, white colors. Appearance of Anthracite is Veined or Pebbled and that of Enderbite is Veined or Pebbled. Properties of rock is another aspect for Anthracite vs Enderbite. The hardness of Anthracite is 1-1.5 and that of Enderbite is 6-7. The types of Anthracite are Semi-anthracite and Meta-anthracite whereas types of Enderbite are -. 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 Enderbite is white. The specific heat capacity of Anthracite is 1.32 kJ/Kg K and that of Enderbite is 0.79 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 Enderbite is heat resistant, wear resistant.
