5 Formation

5.1 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.

Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.

Anthracite vs Mylonite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Anthracite and Mylonite Reserves. Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster. Mylonite is a metamorphic rock formed by ductile deformation during intense shearing encountered during folding and faulting, a process termed cataclastic or dynamic metamorphism. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Anthracite vs Mylonite information and Anthracite vs Mylonite characteristics in the upcoming sections.

The uses of Anthracite in construction industry include Cement manufacture, For road aggregate, Making natural cement, Steel production and that of Mylonite include For road aggregate, Landscaping, Roadstone.

More about Anthracite and Mylonite

Here you can know more about Anthracite and Mylonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anthracite and Mylonite consists of mineral content and compound content. The mineral content of Anthracite includes Calcite, Clay, Clay Minerals and mineral content of Mylonite includes Porphyroblasts. You can also check out the list of all Metamorphic Rocks. When we have to compare Anthracite vs Mylonite, 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, Mylonite is available in black to grey colors. Appearance of Anthracite is Veined or Pebbled and that of Mylonite is Dull, Banded and Foilated. Properties of rock is another aspect for Anthracite vs Mylonite. The hardness of Anthracite is 1-1.5 and that of Mylonite is 3-4. The types of Anthracite are Semi-anthracite and Meta-anthracite whereas types of Mylonite are Blastomylonites, Ultramylonites and Phyllonites. 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 Mylonite is white. The specific heat capacity of Anthracite is 1.32 kJ/Kg K and that of Mylonite is 1.50 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 Mylonite is heat resistant, impact resistant, pressure resistant.
