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
Mudstone is a fine-grained, dark gray sedimentary rock, which is formed from silt and clay and is similar to shale but has less laminations

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.
Mudstone forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are buried and compacted by overlying sediment hence forming mudstone.

Cataclasite vs Mudstone 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. Cataclasite vs Mudstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Cataclasite and Properties of Mudstone. Learn more about Cataclasite vs Mudstone in the next section. The interior uses of Cataclasite include Decorative aggregates and Homes whereas the interior uses of Mudstone include Decorative aggregates, Entryways, Floor tiles and Interior decoration. Due to some exceptional properties of Cataclasite and Mudstone, they have various applications in construction industry. The uses of Cataclasite in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate and that of Mudstone include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Cataclasite and Mudstone
Here you can know more about Cataclasite and Mudstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Cataclasite and Mudstone 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 Mudstone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Cataclasite vs Mudstone, 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, Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Cataclasite is Dull and Banded and that of Mudstone is Rough and Dull. Properties of rock is another aspect for Cataclasite vs Mudstone. The hardness of Cataclasite is 3-4 and that of Mudstone is 2-3. The types of Cataclasite are Protocataclasite, Mesocataclasite, Ultracataclasite and Foliated cataclasite whereas types of Mudstone are Marl, Shale and Argillite. 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 Mudstone is white. The specific heat capacity of Cataclasite is Not Available and that of Mudstone is 0.39 kJ/Kg K. 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 Mudstone is heat resistant, impact resistant.
