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

Anthracite vs Schist 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 Schist characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Anthracite and Properties of Schist. Learn more about Anthracite vs Schist in the next section. The interior uses of Anthracite include Not yet used whereas the interior uses of Schist include Decorative aggregates, Floor tiles and Interior decoration. Due to some exceptional properties of Anthracite and Schist, 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 Schist include As dimension stone, Building houses or walls, Cement manufacture, For road aggregate, Roadstone.
More about Anthracite and Schist
Here you can know more about Anthracite and Schist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anthracite and Schist consists of mineral content and compound content. The mineral content of Anthracite includes Calcite, Clay, Clay Minerals and mineral content of Schist includes Alusite, Amphibole, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Sillimanite, Staurolite, Talc. You can also check out the list of all Metamorphic Rocks. When we have to compare Anthracite vs Schist, 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, Schist is available in black, blue, brown, dark brown, green, grey, silver colors. Appearance of Anthracite is Veined or Pebbled and that of Schist is Layered and Shiny. Properties of rock is another aspect for Anthracite vs Schist. The hardness of Anthracite is 1-1.5 and that of Schist is 3.5-4. The types of Anthracite are Semi-anthracite and Meta-anthracite whereas types of Schist are Mica Schists, Calc-Silicate Schists, Graphite Schists, Blueschists, Whiteschists, Greenschists, Hornblende Schist, Talc Schist, Chlorite Schist, Garnet Schist, Glaucophane schist.. 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 Schist is white. The specific heat capacity of Anthracite is 1.32 kJ/Kg K and that of Schist is Not Available. 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 Schist is impact resistant, pressure resistant, water resistant.
