Gritstone vs Coal

Gritstone 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 Gritstone and Coal Reserves. Gritstone or grit is a hard, coarse-grained, siliceous sandstone. 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 Gritstone vs Coal information and Gritstone vs Coal characteristics in the upcoming sections.

Gritstone 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. Gritstone vs Coal characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Gritstone and Properties of Coal. Learn more about Gritstone vs Coal in the next section. The interior uses of Gritstone include Countertops, Decorative aggregates, Homes and Interior decoration whereas the interior uses of Coal include Not yet used. Due to some exceptional properties of Gritstone and Coal, they have various applications in construction industry. The uses of Gritstone in construction industry include Construction aggregate, Roadstone and that of Coal include Cement manufacture, For road aggregate, Making natural cement, Steel production.

More about Gritstone and Coal

Here you can know more about Gritstone and Coal. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Gritstone and Coal consists of mineral content and compound content. The mineral content of Gritstone includes Calcite, Clay Minerals, Feldspar, Micas, 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 Sedimentary Rocks. When we have to compare Gritstone vs Coal, the texture, color and appearance plays an important role in determining the type of rock. Gritstone is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors whereas, Coal is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Gritstone is Layered and Foliated and that of Coal is Veined or Pebbled. Properties of rock is another aspect for Gritstone vs Coal. The hardness of Gritstone is 6-7 and that of Coal is 1-1.5. The types of Gritstone are Not Available 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 Gritstone is white while that of Coal is black. The specific heat capacity of Gritstone is 0.92 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.Gritstone is heat resistant, impact resistant, pressure resistant whereas Coal is heat resistant.
