Coal vs Sandstone

Coal vs Sandstone 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 Sandstone Reserves. Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds. Sandstone is defined as a rock which is composed of sand-sized grains of various minerals mostly of uniform size and often are smooth and rounded. 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 Sandstone information and Coal vs Sandstone characteristics in the upcoming sections.

Coal vs Sandstone 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 Sandstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Coal and Properties of Sandstone. Learn more about Coal vs Sandstone in the next section. The interior uses of Coal include Not yet used whereas the interior uses of Sandstone include Countertops, Decorative aggregates and Interior decoration. Due to some exceptional properties of Coal and Sandstone, 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 Sandstone include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar.

More about Coal and Sandstone

Here you can know more about Coal and Sandstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Coal and Sandstone 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 Sandstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz.

Coal is available in black, brown, dark brown, grey, light to dark grey colors whereas, Sandstone is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. Appearance of Coal is Veined or Pebbled and that of Sandstone is Rough. Properties of rock is another aspect for Coal vs Sandstone. The hardness of Coal is 1-1.5 and that of Sandstone is 6-7. The types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite whereas types of Sandstone are Grey Sandstones, Crystallized Sandstones, Hard Sandstones , Carbonate Cemented Sandstones and Ganister. 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 Sandstone is white. The specific heat capacity of Coal is 1.32 kJ/Kg K and that of Sandstone is 0.92 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 Sandstone is heat resistant, impact resistant, pressure resistant.
