Coal vs Gritstone

Coal vs Gritstone 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 Gritstone Reserves. Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds. Gritstone or grit is a hard, coarse-grained, siliceous sandstone. 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 Gritstone information and Coal vs Gritstone characteristics in the upcoming sections.

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

More about Coal and Gritstone

Here you can know more about Coal and Gritstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Coal and Gritstone 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 Gritstone includes Calcite, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Coal vs Gritstone, 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, Gritstone 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 Gritstone is Layered and Foliated. Properties of rock is another aspect for Coal vs Gritstone. The hardness of Coal is 1-1.5 and that of Gritstone is 6-7. The types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite whereas types of Gritstone 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 Gritstone is white. The specific heat capacity of Coal is 1.32 kJ/Kg K and that of Gritstone 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 Gritstone is heat resistant, impact resistant, pressure resistant.
