Definition
Luxullianite is a rare type of granite, known for presence of clusters of radially arranged acicular tourmaline crystals which are enclosed by phenocrysts of orthoclase and quartz in a matrix of quartz, tourmaline, alkali feldspar, brown mica.
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
Luxullianite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture. It is found in large plutons on the continents, i.e. in areas where the Earth's crust has been deeply eroded.
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 Luxullianite and Cataclasite
Here you can know more about Luxullianite and Cataclasite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Luxullianite and Cataclasite consists of mineral content and compound content. The mineral content of Luxullianite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz 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 Luxullianite vs Cataclasite, the texture, color and appearance plays an important role in determining the type of rock. Luxullianite is available in black, grey, orange, pink, white colors whereas, Cataclasite is available in brown, green, white, yellow colors. Appearance of Luxullianite is Veined or Pebbled and that of Cataclasite is Dull and Banded. Properties of rock is another aspect for Luxullianite vs Cataclasite. The hardness of Luxullianite is 6-7 and that of Cataclasite is 3-4. The types of Luxullianite are Igneous Protolith Granite, Sedimentary Protolith Granite, Mantle Granite, Anorogenic Granite and Hybrid Granite 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 Luxullianite is white while that of Cataclasite is black. The specific heat capacity of Luxullianite is 0.79 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.Luxullianite is heat resistant, wear resistant whereas Cataclasite is heat resistant, impact resistant, pressure resistant.
