Formation

Formation
Dunite is a plutonic ultramafic igneous rock consisting almost m olivine. It can be formed in two ways.   
Oil Shale forms on the beds of seas and lakes and its formation starts with the organic debris settling and accumulating at the bottom of a lake or sea which are then transformed into rock with the help of high temperature and pressure.

Dunite vs Oil shale 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 Dunite and Oil shale Reserves. Dunite is a green to brownish coarse-grained igneous rock mainly consisting of olivine. Oil Shale is a fine-grained sedimentary rock from which oil is extracted. 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 Dunite vs Oil shale information and Dunite vs Oil shale characteristics in the upcoming sections.

Dunite vs Oil shale 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. Dunite vs Oil shale characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Dunite and Properties of Oil shale. Learn more about Dunite vs Oil shale in the next section. The interior uses of Dunite include Decorative aggregates and Interior decoration whereas the interior uses of Oil shale include Not yet used. Due to some exceptional properties of Dunite and Oil shale, they have various applications in construction industry. The uses of Dunite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar and that of Oil shale include Cement manufacture, Construction aggregate, For road aggregate, Serves as an oil and gas reservoir rock.

More about Dunite and Oil shale

Here you can know more about Dunite and Oil shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dunite and Oil shale consists of mineral content and compound content. The mineral content of Dunite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene and mineral content of Oil shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Dunite vs Oil shale, the texture, color and appearance plays an important role in determining the type of rock. Dunite is available in dark greenish - grey colors whereas, Oil shale is available in black, brown, buff, green, grey, red, yellow colors. Appearance of Dunite is Rough and Shiny and that of Oil shale is Muddy. Properties of rock is another aspect for Dunite vs Oil shale. The hardness of Dunite is 3.5-4 and that of Oil shale is 2-3. The types of Dunite are Not Available whereas types of Oil shale are Carbonate-rich Shale, Siliceous Shale and Cannel Shale. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dunite and Oil shale is white. The specific heat capacity of Dunite is 1.25 kJ/Kg K and that of Oil shale is 0.39 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Dunite is heat resistant, pressure resistant, wear resistant whereas Oil shale is heat resistant, impact resistant.
