Definition
Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities
  
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
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
  
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.

The uses of Scoria in construction industry include Cement manufacture, Construction aggregate, For road aggregate, In landscaping and drainage works and that of Cataclasite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Scoria and Cataclasite
Here you can know more about Scoria and Cataclasite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Scoria and Cataclasite consists of mineral content and compound content. The mineral content of Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica 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 Igneous Rocks. When we have to compare Scoria vs Cataclasite, the texture, color and appearance plays an important role in determining the type of rock. Scoria is available in black, brown, dark grey to black, red colors whereas, Cataclasite is available in brown, green, white, yellow colors. Appearance of Scoria is Glassy and Vesicular and that of Cataclasite is Dull and Banded. Properties of rock is another aspect for Scoria vs Cataclasite. The hardness of Scoria is 5-6 and that of Cataclasite is 3-4. The types of Scoria are Not Available 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 Scoria is white while that of Cataclasite is black. The specific heat capacity of Scoria is Not Available 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.Scoria is heat resistant, impact resistant, pressure resistant, wear resistant whereas Cataclasite is heat resistant, impact resistant, pressure resistant.
