Formation

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

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

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

More about Lignite and Phyllite

Here you can know more about Lignite and Phyllite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Phyllite consists of mineral content and compound content. The mineral content of Lignite is not available and 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. You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Phyllite, 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, Phyllite is available in black to grey, light greenish grey colors. Appearance of Lignite is Veined or Pebbled and that of Phyllite is Crinkled or Wavy. Properties of rock is another aspect for Lignite vs Phyllite. The hardness of Lignite is 1 and that of Phyllite is 1-2. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite whereas types of Phyllite are Not Available. 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 Phyllite is white. The specific heat capacity of Lignite is 1.26 kJ/Kg K and that of Phyllite is Not Available. 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 Phyllite is heat resistant, pressure resistant, water resistant.
