5.1 Formation

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

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 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 Quartzite and Lignite Reserves. Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone. 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 Quartzite vs Lignite information and Quartzite vs Lignite characteristics in the upcoming sections.

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

More about Quartzite and Lignite

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