Coal vs Laterite 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 Laterite Reserves. Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds. Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas. 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 Laterite information and Coal vs Laterite characteristics in the upcoming sections.

Coal vs Laterite 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 Laterite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Coal and Properties of Laterite. Learn more about Coal vs Laterite in the next section. The interior uses of Coal include Not yet used whereas the interior uses of Laterite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Coal and Laterite, 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 Laterite include Cobblestones, For road aggregate, Landscaping, Roadstone.

More about Coal and Laterite

Here you can know more about Coal and Laterite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Coal and Laterite 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 Laterite includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Coal vs Laterite, 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, Laterite is available in brown, buff, red colors. Appearance of Coal is Veined or Pebbled and that of Laterite is Rough and Banded. Properties of rock is another aspect for Coal vs Laterite. The hardness of Coal is 1-1.5 and that of Laterite is 2. The types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite whereas types of Laterite are Not Available. 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 Laterite is white. The specific heat capacity of Coal is 1.32 kJ/Kg K and that of Laterite is Not Available. 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 Laterite is heat resistant, pressure resistant.
