Formation

Formation

Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
Coal forms from the accumulation of plant debris in a swamp environment which is buried by sediments such as mud or sand and then compacted to form coal.

Charnockite vs Coal 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 Charnockite and Coal Reserves. Charnockite is a variety of granite containing minerals like orthopyroxene, quartz, and feldspar. Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds. 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 Charnockite vs Coal information and Charnockite vs Coal characteristics in the upcoming sections.

Charnockite vs Coal 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. Charnockite vs Coal characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Charnockite and Properties of Coal. Learn more about Charnockite vs Coal in the next section. The interior uses of Charnockite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads whereas the interior uses of Coal include . Due to some exceptional properties of Charnockite and Coal, they have various applications in construction industry. The uses of Charnockite in construction industry include As dimension stone and that of Coal include Cement manufacture, For road aggregate, Making natural cement, Steel production.

More about Charnockite and Coal

Here you can know more about Charnockite and Coal. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Charnockite and Coal consists of mineral content and compound content. The mineral content of Charnockite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz and mineral content of Coal includes Analcime, Apatite, Barite, Calcite, Chalcopyrite, Chlorite, Chromite, Clausthalite, Clay Minerals, Crandallite Group, Dolomite, Feldspar, Galena, Gypsum, Marcasite, Muscovite or Illite, Pyrite, Quartz, Siderite, Sphalerite, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Charnockite vs Coal, the texture, color and appearance plays an important role in determining the type of rock. Charnockite is available in black, grey, orange, pink, white colors whereas, Coal is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Charnockite is Veined or Pebbled and that of Coal is Veined or Pebbled. Properties of rock is another aspect for Charnockite vs Coal. The hardness of Charnockite is 6-7 and that of Coal is 1-1.5. The types of Charnockite are Enderbite whereas types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Charnockite is white while that of Coal is black. The specific heat capacity of Charnockite is 0.84 kJ/Kg K and that of Coal is 1.32 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Charnockite is heat resistant, wear resistant whereas Coal is heat resistant.
