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.

Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

Lignite vs Quartzite 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 Quartzite Reserves. Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone. 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 Quartzite information and Lignite vs Quartzite characteristics in the upcoming sections.

Lignite vs Quartzite 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 Quartzite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lignite and Properties of Quartzite. Learn more about Lignite vs Quartzite in the next section. The interior uses of Lignite include Not yet used whereas the interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes. Due to some exceptional properties of Lignite and Quartzite, they have various applications in construction industry. The uses of Lignite in construction industry include For road aggregate, Steel production and that of Quartzite include Arrowheads, As dimension stone, Cement manufacture, Construction aggregate, Cutting tool, For road aggregate, Making natural cement, Production of glass and ceramics, Rail track ballast, Roadstone.

More about Lignite and Quartzite

Here you can know more about Lignite and Quartzite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Quartzite consists of mineral content and compound content. The mineral content of Lignite is not available and mineral content of Quartzite includes Chlorite, Epidote, Hematite, Kyanite, Magnetite, Muscovite or Illite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Quartzite, 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, Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. Appearance of Lignite is Veined or Pebbled and that of Quartzite is Lustrous. Properties of rock is another aspect for Lignite vs Quartzite. The hardness of Lignite is 1 and that of Quartzite is 6-7. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite whereas types of Quartzite 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 Quartzite is white. The specific heat capacity of Lignite is 1.26 kJ/Kg K and that of Quartzite is 0.75 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 Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant.
