Quartzite vs Coal

Quartzite 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 Quartzite and Coal Reserves. Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz 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 Quartzite vs Coal information and Quartzite vs Coal characteristics in the upcoming sections.

Quartzite 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. Quartzite vs Coal characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Quartzite and Properties of Coal. Learn more about Quartzite vs Coal in the next section. The interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes whereas the interior uses of Coal include Not yet used. Due to some exceptional properties of Quartzite and Coal, they have various applications in construction industry. The uses of Quartzite in construction industry include Arrowheads, As dimension stone, Cement manufacture, Construction aggregate, Cutting tool, For road aggregate, Making natural cement, Production of glass and ceramics, Rail track ballast, Roadstone and that of Coal include Cement manufacture, For road aggregate, Making natural cement, Steel production.

More about Quartzite and Coal

Here you can know more about Quartzite and Coal. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock.

You can also check out the list of all Metamorphic Rocks. When we have to compare Quartzite vs Coal, the texture, color and appearance plays an important role in determining the type of rock. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas, Coal is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Quartzite is Lustrous and that of Coal is Veined or Pebbled. Properties of rock is another aspect for Quartzite vs Coal. The hardness of Quartzite is 6-7 and that of Coal is 1-1.5. The types of Quartzite 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 Quartzite is white while that of Coal is black. The specific heat capacity of Quartzite is 0.75 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.Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Coal is heat resistant.
