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

Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of Earth

5.1 Formation

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

Basalt forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.

Mylonite vs Basalt 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 Basalt 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. Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of Earth. 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. You can check out Mylonite vs Basalt information and Mylonite vs Basalt characteristics in the upcoming sections.

More about Mylonite and Basalt

Here you can know more about Mylonite and Basalt. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mylonite and Basalt consists of mineral content and compound content. The mineral content of Mylonite includes Porphyroblasts and mineral content of Basalt includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Metamorphic Rocks. When we have to compare Mylonite vs Basalt, the texture, color and appearance plays an important role in determining the type of rock. Mylonite is available in black to grey colors whereas, Basalt is available in black, brown, light to dark grey colors. Appearance of Mylonite is Dull, Banded and Foilated and that of Basalt is Dull and Soft. Properties of rock is another aspect for Mylonite vs Basalt. The hardness of Mylonite is 3-4 and that of Basalt is 6. The types of Mylonite are Blastomylonites, Ultramylonites and Phyllonites whereas types of Basalt are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mylonite is white while that of Basalt is white to grey. The specific heat capacity of Mylonite is 1.50 kJ/Kg K and that of Basalt 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.Mylonite is heat resistant, impact resistant, pressure resistant whereas Basalt is heat resistant, pressure resistant, wear resistant.
