Formation
Pyrolite 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.

Pyrolite 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. Pyrolite vs Oil shale characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Pyrolite and Properties of Oil shale. Learn more about Pyrolite vs Oil shale in the next section. The interior uses of Pyrolite include Decorative aggregates and Interior decoration whereas the interior uses of Oil shale include Not yet used. Due to some exceptional properties of Pyrolite and Oil shale, they have various applications in construction industry. The uses of Pyrolite in construction industry include As dimension stone, Cobblestones and that of Oil shale include Cement manufacture, Construction aggregate, For road aggregate, Serves as an oil and gas reservoir rock.
More about Pyrolite and Oil shale
Here you can know more about Pyrolite and Oil shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Pyrolite and Oil shale consists of mineral content and compound content. The mineral content of Pyrolite 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 Pyrolite vs Oil shale, the texture, color and appearance plays an important role in determining the type of rock. Pyrolite is available in dark greenish - grey colors whereas, Oil shale is available in black, brown, buff, green, grey, red, yellow colors. Appearance of Pyrolite is Rough and Shiny and that of Oil shale is Muddy. Properties of rock is another aspect for Pyrolite vs Oil shale. The hardness of Pyrolite is 5.5-6 and that of Oil shale is 2-3. The types of Pyrolite are Dunite, Wehrlite, Harzburgite, Lherzolite 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 Pyrolite and Oil shale is white. The specific heat capacity of Pyrolite 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.Pyrolite is heat resistant, pressure resistant, wear resistant whereas Oil shale is heat resistant, impact resistant.
