Definition
Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel
Mylonite is a metamorphic rock formed by ductile deformation during intense shearing encountered during folding and faulting, a process termed cataclastic or dynamic metamorphism

Formation
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.

More about Flint and Mylonite
Here you can know more about Flint and Mylonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Flint and Mylonite consists of mineral content and compound content. The mineral content of Flint includes Silicon and mineral content of Mylonite includes Porphyroblasts. You can also check out the list of all Sedimentary Rocks. When we have to compare Flint vs Mylonite, the texture, color and appearance plays an important role in determining the type of rock. Flint is available in black, brown, green, grey, red, white colors whereas, Mylonite is available in black to grey colors. Appearance of Flint is Glassy or Pearly and that of Mylonite is Dull, Banded and Foilated. Properties of rock is another aspect for Flint vs Mylonite. The hardness of Flint is 7 and that of Mylonite is 3-4. The types of Flint are Not Available whereas types of Mylonite are Blastomylonites, Ultramylonites and Phyllonites. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Flint and Mylonite is white. The specific heat capacity of Flint is 0.74 kJ/Kg K and that of Mylonite is 1.50 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Flint is heat resistant, impact resistant, pressure resistant, wear resistant whereas Mylonite is heat resistant, impact resistant, pressure resistant.
