Definition
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone
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

Features
Generally rough to touch, Is one of the oldest rock
Easily splits into thin plates, Is one of the oldest rock
Archaeological Significance
Formation
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
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.

Quartzite 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. Quartzite vs Cataclasite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Quartzite and Properties of Cataclasite. Learn more about Quartzite vs Cataclasite in the next section. The interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes whereas the interior uses of Cataclasite include Decorative aggregates and Homes. Due to some exceptional properties of Quartzite and Cataclasite, they have various applications in construction industry. The uses of Quartzite in construction industry include Arrowheads, As dimension stone, Cement manufacture, Construction aggregate, Cutting tool, For road aggregate, Making natural cement, Production of glass and ceramics, Rail track ballast, Roadstone and that of Cataclasite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Quartzite and Cataclasite
Here you can know more about Quartzite and Cataclasite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Quartzite and Cataclasite consists of mineral content and compound content. The mineral content of Quartzite includes Chlorite, Epidote, Hematite, Kyanite, Magnetite, Muscovite or Illite, 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 Metamorphic Rocks. When we have to compare Quartzite vs Cataclasite, the texture, color and appearance plays an important role in determining the type of rock. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas, Cataclasite is available in brown, green, white, yellow colors. Appearance of Quartzite is Lustrous and that of Cataclasite is Dull and Banded. Properties of rock is another aspect for Quartzite vs Cataclasite. The hardness of Quartzite is 6-7 and that of Cataclasite is 3-4. The types of Quartzite are Orthoquartzite and Metaquartzite 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 Quartzite is white while that of Cataclasite is black. The specific heat capacity of Quartzite is 0.75 kJ/Kg K and that of Cataclasite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Cataclasite is heat resistant, impact resistant, pressure resistant.
