Archaeological Significance
Formation
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.
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 Whiteschist and Anthracite
Here you can know more about Whiteschist and Anthracite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Whiteschist and Anthracite consists of mineral content and compound content. The mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica 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 Whiteschist vs Anthracite, the texture, color and appearance plays an important role in determining the type of rock. Whiteschist is available in green, grey, white colors whereas, Anthracite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Whiteschist is Banded and Foilated and that of Anthracite is Veined or Pebbled. Properties of rock is another aspect for Whiteschist vs Anthracite. The hardness of Whiteschist is 1.5 and that of Anthracite is 1-1.5. The types of Whiteschist are - 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 Whiteschist is white while that of Anthracite is black. The specific heat capacity of Whiteschist is 0.92 kJ/Kg K and that of Anthracite is 1.32 kJ/Kg K.
