5 Formation

5.1 Formation

Picrite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

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.

Picrite 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 Picrite and Oil shale Reserves. Picrite is a variety of high-magnesium olivine basalt that is very rich in the mineral 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 Picrite vs Oil shale information and Picrite vs Oil shale characteristics in the upcoming sections.

Picrite 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. Picrite vs Oil shale characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Picrite and Properties of Oil shale. Learn more about Picrite vs Oil shale in the next section. The interior uses of Picrite include Countertops, Decorative aggregates, Homes and Interior decoration whereas the interior uses of Oil shale include Not yet used. Due to some exceptional properties of Picrite and Oil shale, they have various applications in construction industry. The uses of Picrite in construction industry include As a sintering agent in steel industry to process iron ore, Cement manufacture, For road aggregate, Manufacture of magnesium and dolomite refractories, Roadstone, Used for flooring, stair treads, borders and window sills. and that of Oil shale include Cement manufacture, Construction aggregate, For road aggregate, Serves as an oil and gas reservoir rock.

More about Picrite and Oil shale

Here you can know more about Picrite and Oil shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Picrite and Oil shale consists of mineral content and compound content. The mineral content of Picrite includes Biotite, Olivine, Plagioclase, Pyrrhotite 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 Picrite vs Oil shale, the texture, color and appearance plays an important role in determining the type of rock. Picrite is available in black, brown, colourless, green, grey, pink, white, yellow colors whereas, Oil shale is available in black, brown, buff, green, grey, red, yellow colors. Appearance of Picrite is Rough and Shiny and that of Oil shale is Muddy. Properties of rock is another aspect for Picrite vs Oil shale. The hardness of Picrite is 6.8 and that of Oil shale is 2-3. The types of Picrite are Oceanite 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 Picrite and Oil shale is white, greenish white or grey. The specific heat capacity of Picrite is 0.88 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.Picrite is heat resistant whereas Oil shale is heat resistant, impact resistant.
