Definition
A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.
Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster

Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite 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.

Serpentinite vs Anthracite 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. Serpentinite vs Anthracite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Serpentinite and Properties of Anthracite. Learn more about Serpentinite vs Anthracite in the next section. The interior uses of Serpentinite include Decorative aggregates and Interior decoration whereas the interior uses of Anthracite include Not yet used. Due to some exceptional properties of Serpentinite and Anthracite, they have various applications in construction industry. The uses of Serpentinite in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement and that of Anthracite include Cement manufacture, For road aggregate, Making natural cement, Steel production.
More about Serpentinite and Anthracite
Here you can know more about Serpentinite and Anthracite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Anthracite consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Anthracite includes Calcite, Clay, Clay Minerals. You can also check out the list of all . When we have to compare Serpentinite vs Anthracite, the texture, color and appearance plays an important role in determining the type of rock. Serpentinite is available in black, brown, colourless, green, grey, white colors whereas, Anthracite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Serpentinite is Rough and Dull and that of Anthracite is Veined or Pebbled. Properties of rock is another aspect for Serpentinite vs Anthracite. The hardness of Serpentinite is 3-5 and that of Anthracite is 1-1.5. The types of Serpentinite are Jadeitite 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 Serpentinite is white, greenish white or grey while that of Anthracite is black. The specific heat capacity of Serpentinite is 0.95 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.Serpentinite is heat resistant whereas Anthracite is heat resistant, water resistant.
