5 Formation

5.1 Formation

Coal formation takes place due to accumulation of plant debris in a swamp environment. The Coal formation process continues, as peat turns into lignite brown or black coal at increasing heat and pressure.

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

Lignite 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 Lignite and Mylonite Reserves. Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. 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 Lignite vs Mylonite information and Lignite vs Mylonite characteristics in the upcoming sections.

Lignite vs Mylonite 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. Lignite vs Mylonite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lignite and Properties of Mylonite. Learn more about Lignite vs Mylonite in the next section. The interior uses of Lignite include Not yet used whereas the interior uses of Mylonite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Lignite and Mylonite, they have various applications in construction industry. The uses of Lignite in construction industry include For road aggregate, Steel production and that of Mylonite include For road aggregate, Landscaping, Roadstone.

More about Lignite and Mylonite

Here you can know more about Lignite and Mylonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Mylonite consists of mineral content and compound content. The mineral content of Lignite is not available and mineral content of Mylonite includes Porphyroblasts. You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Mylonite, the texture, color and appearance plays an important role in determining the type of rock. Lignite is available in black, brown, dark brown, grey, light to dark grey colors whereas, Mylonite is available in black to grey colors. Appearance of Lignite is Veined or Pebbled and that of Mylonite is Dull, Banded and Foilated. Properties of rock is another aspect for Lignite vs Mylonite. The hardness of Lignite is 1 and that of Mylonite is 3-4. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite 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 Lignite is black while that of Mylonite is white. The specific heat capacity of Lignite is 1.26 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.Lignite is heat resistant whereas Mylonite is heat resistant, impact resistant, pressure resistant.
