Archaeological Significance
Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
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 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. Laterite vs Oil shale characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Laterite and Properties of Oil shale. Learn more about Laterite vs Oil shale in the next section. The interior uses of Laterite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Oil shale include . Due to some exceptional properties of Laterite and Oil shale, they have various applications in construction industry. The uses of Laterite in construction industry include Cobblestones, For road aggregate, Landscaping, Roadstone and that of Oil shale include Cement manufacture, Construction aggregate, For road aggregate, Serves as an oil and gas reservoir rock.
More about Laterite and Oil shale
Here you can know more about Laterite and Oil shale. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Laterite and Oil shale consists of mineral content and compound content. The mineral content of Laterite includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, 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 Sedimentary Rocks. When we have to compare Laterite vs Oil shale, the texture, color and appearance plays an important role in determining the type of rock. Laterite is available in brown, buff, red colors whereas, Oil shale is available in black, brown, buff, green, grey, red, yellow colors. Appearance of Laterite is Rough and Banded and that of Oil shale is Muddy. Properties of rock is another aspect for Laterite vs Oil shale. The hardness of Laterite is 2 and that of Oil shale is 2-3. The types of Laterite are Laterite 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 Laterite and Oil shale is white. The specific heat capacity of Laterite is 0.92 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.Laterite is heat resistant, pressure resistant whereas Oil shale is heat resistant, impact resistant.
