Formation
The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.
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.

Appinite 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. Appinite vs Oil shale characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Appinite and Properties of Oil shale. Learn more about Appinite vs Oil shale in the next section. The interior uses of Appinite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Oil shale include Not yet used. Due to some exceptional properties of Appinite and Oil shale, they have various applications in construction industry. The uses of Appinite in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Oil shale include Cement manufacture, Construction aggregate, For road aggregate, Serves as an oil and gas reservoir rock.
More about Appinite and Oil shale
Here you can know more about Appinite and Oil shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Appinite and Oil shale consists of mineral content and compound content. The mineral content of Appinite includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, 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 Appinite vs Oil shale, the texture, color and appearance plays an important role in determining the type of rock. Appinite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas, Oil shale is available in black, brown, buff, green, grey, red, yellow colors. Appearance of Appinite is Dull, Banded and Foilated and that of Oil shale is Muddy. Properties of rock is another aspect for Appinite vs Oil shale. The hardness of Appinite is 5-6 and that of Oil shale is 2-3. The types of Appinite 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 Appinite and Oil shale is white. The specific heat capacity of Appinite is Not Available 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.Appinite is heat resistant, impact resistant whereas Oil shale is heat resistant, impact resistant.
