1 Definition

1.1 Definition

Mylonite is a metamorphic rock formed by ductile deformation during intense shearing encountered during folding and faulting, a process termed cataclastic or dynamic metamorphism

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

5 Formation

5.1 Formation

Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.

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.

Mylonite vs Mudstone Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Mylonite and Mudstone Reserves. Mylonite is a metamorphic rock formed by ductile deformation during intense shearing encountered during folding and faulting, a process termed cataclastic or dynamic metamorphism. 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. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes.

More about Mylonite and Mudstone

Here you can know more about Mylonite and Mudstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mylonite and Mudstone consists of mineral content and compound content. The mineral content of Mylonite includes Porphyroblasts 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 Mylonite vs Mudstone, the texture, color and appearance plays an important role in determining the type of rock. Mylonite is available in black to grey colors whereas, Mudstone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Mylonite is Dull, Banded and Foilated and that of Mudstone is Rough and Dull. Properties of rock is another aspect for Mylonite vs Mudstone. The hardness of Mylonite is 3-4 and that of Mudstone is 2-3. The types of Mylonite are Blastomylonites, Ultramylonites and Phyllonites 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 Mylonite and Mudstone is white. The specific heat capacity of Mylonite is 1.50 kJ/Kg K 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.Mylonite is heat resistant, impact resistant, pressure resistant whereas Mudstone is heat resistant, impact resistant.
