Definition
Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds
  
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

Formation
Coal forms from the accumulation of plant debris in a swamp environment which is buried by sediments such as mud or sand and then compacted to form coal.
  
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.

Coal vs Cataclasite 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. Coal vs Cataclasite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Coal and Properties of Cataclasite. Learn more about Coal vs Cataclasite in the next section. The interior uses of Coal include Not yet used whereas the interior uses of Cataclasite include Decorative aggregates and Homes. Due to some exceptional properties of Coal and Cataclasite, they have various applications in construction industry. The uses of Coal in construction industry include Cement manufacture, For road aggregate, Making natural cement, Steel production and that of Cataclasite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Coal and Cataclasite
Here you can know more about Coal and Cataclasite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Coal and Cataclasite consists of mineral content and compound content. The mineral content of Coal includes Analcime, Apatite, Barite, Calcite, Chalcopyrite, Chlorite, Chromite, Clausthalite, Clay Minerals, Crandallite Group, Dolomite, Feldspar, Galena, Gypsum, Marcasite, Muscovite or Illite, Pyrite, Quartz, Siderite, Sphalerite, Zircon 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 Coal vs Cataclasite, the texture, color and appearance plays an important role in determining the type of rock. Coal is available in black, brown, dark brown, grey, light to dark grey colors whereas, Cataclasite is available in brown, green, white, yellow colors. Appearance of Coal is Veined or Pebbled and that of Cataclasite is Dull and Banded. Properties of rock is another aspect for Coal vs Cataclasite. The hardness of Coal is 1-1.5 and that of Cataclasite is 3-4. The types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite 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 Coal and Cataclasite is black. The specific heat capacity of Coal is 1.32 kJ/Kg K and that of Cataclasite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Coal is heat resistant whereas Cataclasite is heat resistant, impact resistant, pressure resistant.
