5 Formation

5.1 Formation

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.

Lherzolite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Coal vs Lherzolite 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 Coal and Lherzolite Reserves. Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds. Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions. 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 Coal vs Lherzolite information and Coal vs Lherzolite characteristics in the upcoming sections.

Coal vs Lherzolite 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. Coal vs Lherzolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Coal and Properties of Lherzolite. Learn more about Coal vs Lherzolite in the next section. The interior uses of Coal include Not yet used whereas the interior uses of Lherzolite include Decorative aggregates, Entryways, Homes and Interior decoration. Due to some exceptional properties of Coal and Lherzolite, they have various applications in construction industry. The uses of Coal in construction industry include Cement manufacture, For road aggregate, Making natural cement, Steel production and that of Lherzolite include Landscaping, Manufacture of magnesium and dolomite refractories, Used for flooring, stair treads, borders and window sills..

More about Coal and Lherzolite

Here you can know more about Coal and Lherzolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Coal and Lherzolite consists of mineral content and compound content. The 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 and mineral content of Lherzolite includes Harzburgite, Olivine, Pyroxene, Pyrrhotite. You can also check out the list of all . When we have to compare Coal vs Lherzolite, the texture, color and appearance plays an important role in determining the type of rock. Coal is available in black, brown, dark brown, grey, light to dark grey colors whereas, Lherzolite is available in black, dark greenish - grey, green, pink, purple colors. Appearance of Coal is Veined or Pebbled and that of Lherzolite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Coal vs Lherzolite. The hardness of Coal is 1-1.5 and that of Lherzolite is 6.5. The types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite whereas types of Lherzolite are Garnet Lherzolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Coal is black while that of Lherzolite is white. The specific heat capacity of Coal is 1.32 kJ/Kg K and that of Lherzolite is 0.95 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Coal is heat resistant whereas Lherzolite is heat resistant, impact resistant, pressure resistant, wear resistant.
