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.
Whiteschist is formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

More about Anthracite and Whiteschist
Here you can know more about Anthracite and Whiteschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anthracite and Whiteschist consists of mineral content and compound content. The mineral content of Anthracite includes Calcite, Clay, Clay Minerals and mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica. You can also check out the list of all Metamorphic Rocks. When we have to compare Anthracite vs Whiteschist, 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, Whiteschist is available in colourless, green, grey, white colors. Appearance of Anthracite is Veined or Pebbled and that of Whiteschist is Banded and Foilated. Properties of rock is another aspect for Anthracite vs Whiteschist. The hardness of Anthracite is 1-1.5 and that of Whiteschist is 1.5. The types of Anthracite are Semi-anthracite and Meta-anthracite whereas types of Whiteschist 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 Whiteschist is white. The specific heat capacity of Anthracite is 1.32 kJ/Kg K and that of Whiteschist is 0.92 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 Whiteschist is heat resistant.
