5 Formation

5.1 Formation

Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.

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.

Phyllite vs Lignite 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 Phyllite and Lignite Reserves. Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks. Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. 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 Phyllite vs Lignite information and Phyllite vs Lignite characteristics in the upcoming sections.

Phyllite vs Lignite 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. Phyllite vs Lignite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Phyllite and Properties of Lignite. Learn more about Phyllite vs Lignite in the next section. The interior uses of Phyllite include Decorative aggregates, Floor tiles, Homes and Interior decoration whereas the interior uses of Lignite include Not yet used. Due to some exceptional properties of Phyllite and Lignite, they have various applications in construction industry. The uses of Phyllite in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Raw material for the manufacture of mortar, Roadstone and that of Lignite include For road aggregate, Steel production.

More about Phyllite and Lignite

Here you can know more about Phyllite and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Phyllite and Lignite consists of mineral content and compound content. The mineral content of Phyllite includes Albite, Alusite, Amphibole, Apatite, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Sillimanite, Staurolite, Talc, Zircon and mineral content of Lignite is not available. You can also check out the list of all Metamorphic Rocks. When we have to compare Phyllite vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. Phyllite is available in black to grey, light greenish grey colors whereas, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Phyllite is Crinkled or Wavy and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Phyllite vs Lignite. The hardness of Phyllite is 1-2 and that of Lignite is 1. The types of Phyllite are Not Available whereas types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Phyllite is white while that of Lignite is black. The specific heat capacity of Phyllite is Not Available and that of Lignite is 1.26 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Phyllite is heat resistant, pressure resistant, water resistant whereas Lignite is heat resistant.
