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
A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles

Archaeological Significance
Formation
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

More about Mylonite and Turbidite
Here you can know more about Mylonite and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mylonite and Turbidite consists of mineral content and compound content. The mineral content of Mylonite includes Porphyroblasts and mineral content of Turbidite includes Coesite, Quartz, Sand. You can also check out the list of all Metamorphic Rocks. When we have to compare Mylonite vs Turbidite, the texture, color and appearance plays an important role in determining the type of rock. Mylonite is available in black to grey colors whereas, Turbidite is available in black, brown, green, grey, pink colors. Appearance of Mylonite is Dull, Banded and Foilated and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Mylonite vs Turbidite. The hardness of Mylonite is 3-4 and that of Turbidite is 3. The types of Mylonite are Blastomylonites, Ultramylonites and Phyllonites whereas types of Turbidite are Sedimentary rock. 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 Turbidite is white, greenish white or grey. The specific heat capacity of Mylonite is 1.50 kJ/Kg K and that of Turbidite is 0.92 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 Turbidite is heat resistant.
