5 Formation

5.1 Formation

Coal forms from the accumulation of plant debris in a swamp environment which is buried by sediments such as mud or sand and then compacted to form coal.

Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.

Coal vs Peridotite 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 Peridotite Reserves. Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds. Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle. 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 Peridotite information and Coal vs Peridotite characteristics in the upcoming sections.

Coal vs Peridotite 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 Peridotite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Coal and Properties of Peridotite. Learn more about Coal vs Peridotite in the next section. The interior uses of Coal include Not yet used whereas the interior uses of Peridotite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Coal and Peridotite, 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 Peridotite include As dimension stone, Cobblestones.

More about Coal and Peridotite

Here you can know more about Coal and Peridotite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Coal and Peridotite 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 Peridotite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Coal vs Peridotite, 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, Peridotite is available in dark greenish - grey colors. Appearance of Coal is Veined or Pebbled and that of Peridotite is Rough and Shiny. Properties of rock is another aspect for Coal vs Peridotite. The hardness of Coal is 1-1.5 and that of Peridotite is 5.5-6. The types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite whereas types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite. 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 Peridotite is white. The specific heat capacity of Coal is 1.32 kJ/Kg K and that of Peridotite is 1.26 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 Peridotite is heat resistant, pressure resistant, wear resistant.
