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.
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

Oil shale vs Quartzite 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 Quartzite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Oil shale and Properties of Quartzite. Learn more about Oil shale vs Quartzite in the next section. The interior uses of Oil shale include whereas the interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes. Due to some exceptional properties of Oil shale and Quartzite, 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 Quartzite include Arrowheads, As dimension stone, Cement manufacture, Construction aggregate, Cutting tool, For road aggregate, Making natural cement, Production of glass and ceramics, Rail track ballast, Roadstone.
More about Oil shale and Quartzite
Here you can know more about Oil shale and Quartzite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oil shale and Quartzite 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 Quartzite includes Chlorite, Epidote, Hematite, Kyanite, Magnetite, Muscovite or Illite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Oil shale vs Quartzite, 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, Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. Appearance of Oil shale is Muddy and that of Quartzite is Lustrous. Properties of rock is another aspect for Oil shale vs Quartzite. The hardness of Oil shale is 2-3 and that of Quartzite is 6-7. The types of Oil shale are Carbonate-rich Shale, Siliceous Shale and Cannel Shale whereas types of Quartzite are Orthoquartzite and Metaquartzite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Oil shale and Quartzite is white. The specific heat capacity of Oil shale is 0.39 kJ/Kg K and that of Quartzite is 0.75 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 Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant.
