Definition
Trachyandesite is an extrusive igneous rock.
  
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
Trachyandesite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
  
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.

More about Trachyandesite and Cataclasite
Here you can know more about Trachyandesite and Cataclasite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Trachyandesite and Cataclasite consists of mineral content and compound content. The mineral content of Trachyandesite includes Alkali feldspar, Biotite, Olivine, Plagioclase, Pyroxene, Sodic plagioclase 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 Trachyandesite vs Cataclasite, the texture, color and appearance plays an important role in determining the type of rock. Trachyandesite is available in black, brown, light to dark grey colors whereas, Cataclasite is available in brown, green, white, yellow colors. Appearance of Trachyandesite is Dull and Soft and that of Cataclasite is Dull and Banded. Properties of rock is another aspect for Trachyandesite vs Cataclasite. The hardness of Trachyandesite is 4-5 and that of Cataclasite is 3-4. The types of Trachyandesite are Basaltic Trachyandesite 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 Trachyandesite is light to dark brown while that of Cataclasite is black. The specific heat capacity of Trachyandesite is 0.84 kJ/Kg K and that of Cataclasite is Not Available.
