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.

Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

Lignite vs Charnockite 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 Charnockite Reserves. Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. Charnockite is a variety of granite containing minerals like orthopyroxene, quartz, and feldspar. 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 Charnockite information and Lignite vs Charnockite characteristics in the upcoming sections.

Lignite vs Charnockite 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 Charnockite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lignite and Properties of Charnockite. Learn more about Lignite vs Charnockite in the next section. The interior uses of Lignite include Not yet used whereas the interior uses of Charnockite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads. Due to some exceptional properties of Lignite and Charnockite, they have various applications in construction industry. The uses of Lignite in construction industry include For road aggregate, Steel production and that of Charnockite include As dimension stone.

More about Lignite and Charnockite

Here you can know more about Lignite and Charnockite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Charnockite consists of mineral content and compound content. The mineral content of Lignite is not available and mineral content of Charnockite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Charnockite, 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, Charnockite is available in black, grey, orange, pink, white colors. Appearance of Lignite is Veined or Pebbled and that of Charnockite is Veined or Pebbled. Properties of rock is another aspect for Lignite vs Charnockite. The hardness of Lignite is 1 and that of Charnockite is 6-7. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite whereas types of Charnockite are Enderbite. 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 Charnockite is white. The specific heat capacity of Lignite is 1.26 kJ/Kg K and that of Charnockite 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 Charnockite is heat resistant, wear resistant.
