Definition
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
  
Blueschist is a metamorphic rock which is generally blue in color and is formed under conditions of high pressure and low temperature

Formation
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.
  
Blueschist forms due to the metamorphism of basalt and other rocks with similar composition at high pressures and low temperatures and approximately corresponding to a depth of 15 to 30 kilometers and 200 to 500 °C.

More about Cataclasite and Blueschist
Here you can know more about Cataclasite and Blueschist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Cataclasite and Blueschist consists of mineral content and compound content. The mineral content of Cataclasite includes Albite, Apatite, Augite, Biotite, Calcite, Enstatite, Epidote, Feldspar, Micas, Muscovite or Illite, Pyroxene, Quartz and mineral content of Blueschist includes Albite, Chlorite, Epidote, Garnet, Glaucophane, Lawsonite, Muscovite or Illite, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Cataclasite vs Blueschist, the texture, color and appearance plays an important role in determining the type of rock. Cataclasite is available in brown, green, white, yellow colors whereas, Blueschist is available in blue, bluish - grey, purple, shades of blue colors. Appearance of Cataclasite is Dull and Banded and that of Blueschist is Dull and Banded. Properties of rock is another aspect for Cataclasite vs Blueschist. The hardness of Cataclasite is 3-4 and that of Blueschist is 3.5-4. The types of Cataclasite are Protocataclasite, Mesocataclasite, Ultracataclasite and Foliated cataclasite whereas types of Blueschist are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Cataclasite is black while that of Blueschist is white to grey. The specific heat capacity of Cataclasite is Not Available and that of Blueschist is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Cataclasite is heat resistant, impact resistant, pressure resistant whereas Blueschist is impact resistant, pressure resistant.
