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
Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone

Host Rock for Lead, Is one of the oldest rock
Archaeological Significance
Formation
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

More about Mylonite and Diamictite
Here you can know more about Mylonite and Diamictite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mylonite and Diamictite consists of mineral content and compound content. The mineral content of Mylonite includes Porphyroblasts and mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Mylonite vs Diamictite, the texture, color and appearance plays an important role in determining the type of rock. Mylonite is available in black to grey colors whereas, Diamictite is available in brown, buff colors. Appearance of Mylonite is Dull, Banded and Foilated and that of Diamictite is Banded. Properties of rock is another aspect for Mylonite vs Diamictite. The hardness of Mylonite is 3-4 and that of Diamictite is 2-3. The types of Mylonite are Blastomylonites, Ultramylonites and Phyllonites whereas types of Diamictite are Bedded Diamictite and Laminated Diamictite. 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 Diamictite is light to dark brown. The specific heat capacity of Mylonite is 1.50 kJ/Kg K and that of Diamictite is 0.75 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 Diamictite is heat resistant, impact resistant.
