Archaeological Significance
Formation
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.
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

Oil shale vs Laterite 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. Oil shale vs Laterite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Oil shale and Properties of Laterite. Learn more about Oil shale vs Laterite in the next section. The interior uses of Oil shale include whereas the interior uses of Laterite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Oil shale and Laterite, they have various applications in construction industry. The uses of Oil shale in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Serves as an oil and gas reservoir rock and that of Laterite include Cobblestones, For road aggregate, Landscaping, Roadstone.
More about Oil shale and Laterite
Here you can know more about Oil shale and Laterite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oil shale and Laterite consists of mineral content and compound content. The mineral content of Oil shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides and mineral content of Laterite includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Oil shale vs Laterite, the texture, color and appearance plays an important role in determining the type of rock. Oil shale is available in black, brown, buff, green, grey, red, yellow colors whereas, Laterite is available in brown, buff, red colors. Appearance of Oil shale is Muddy and that of Laterite is Rough and Banded. Properties of rock is another aspect for Oil shale vs Laterite. The hardness of Oil shale is 2-3 and that of Laterite is 2. The types of Oil shale are Carbonate-rich Shale, Siliceous Shale and Cannel Shale whereas types of Laterite are Laterite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Oil shale and Laterite is white. The specific heat capacity of Oil shale is 0.39 kJ/Kg K and that of Laterite is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Oil shale is heat resistant, impact resistant whereas Laterite is heat resistant, pressure resistant.
