Definition
Oil Shale is a fine-grained sedimentary rock from which oil is extracted
Cataclasite is a type of cataclastic rock that is formed by fracturing and comminution during faulting. It is normally cohesive and non-foliated, consisting of angular clasts in a finer-grained matrix

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.
Cataclasiste rocks mainly form by pressure deep under the Earth's surface, from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Due to some exceptional properties of Oil shale and Cataclasite, 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 Cataclasite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Oil shale and Cataclasite
Here you can know more about Oil shale and Cataclasite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oil shale and Cataclasite 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 Cataclasite includes Albite, Apatite, Augite, Biotite, Calcite, Enstatite, Epidote, Feldspar, Micas, Muscovite or Illite, Pyroxene, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Oil shale vs Cataclasite, 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, Cataclasite is available in brown, green, white, yellow colors. Appearance of Oil shale is Muddy and that of Cataclasite is Dull and Banded. Properties of rock is another aspect for Oil shale vs Cataclasite. The hardness of Oil shale is 2-3 and that of Cataclasite is 3-4. The types of Oil shale are Carbonate-rich Shale, Siliceous Shale and Cannel Shale whereas types of Cataclasite are Protocataclasite, Mesocataclasite, Ultracataclasite and Foliated cataclasite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Oil shale is white while that of Cataclasite is black. The specific heat capacity of Oil shale is 0.39 kJ/Kg K and that of Cataclasite is 0.84 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 Cataclasite is heat resistant, impact resistant, pressure resistant.
