5 Formation

5.1 Formation

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 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.

Peridotite 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 Peridotite and Coal Reserves. Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle. 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 Peridotite vs Coal information and Peridotite vs Coal characteristics in the upcoming sections.

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

More about Peridotite and Coal

Here you can know more about Peridotite and Coal. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Peridotite and Coal consists of mineral content and compound content. The mineral content of Peridotite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene 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 Igneous Rocks. When we have to compare Peridotite vs Coal, the texture, color and appearance plays an important role in determining the type of rock. Peridotite is available in dark greenish - grey colors whereas, Coal is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Peridotite is Rough and Shiny and that of Coal is Veined or Pebbled. Properties of rock is another aspect for Peridotite vs Coal. The hardness of Peridotite is 5.5-6 and that of Coal is 1-1.5. The types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite 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 Peridotite is white while that of Coal is black. The specific heat capacity of Peridotite is 1.26 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.Peridotite is heat resistant, pressure resistant, wear resistant whereas Coal is heat resistant.
