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
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

Archaeological Significance
Formation
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

Mylonite vs Conglomerate Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Mylonite vs Conglomerate characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mylonite and Properties of Conglomerate. Learn more about Mylonite vs Conglomerate in the next section. The interior uses of Mylonite include Decorative aggregates and Interior decoration whereas the interior uses of Conglomerate include Decorative aggregates, Floor tiles and Homes. Due to some exceptional properties of Mylonite and Conglomerate, they have various applications in construction industry. The uses of Mylonite in construction industry include For road aggregate, Landscaping, Roadstone and that of Conglomerate include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Roadstone.
More about Mylonite and Conglomerate
Here you can know more about Mylonite and Conglomerate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mylonite and Conglomerate consists of mineral content and compound content. The mineral content of Mylonite includes Porphyroblasts and mineral content of Conglomerate includes Clay, Sand, Silica, Silt. You can also check out the list of all Metamorphic Rocks. When we have to compare Mylonite vs Conglomerate, the texture, color and appearance plays an important role in determining the type of rock. Mylonite is available in black to grey colors whereas, Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. Appearance of Mylonite is Dull, Banded and Foilated and that of Conglomerate is Shiny and Rounded. Properties of rock is another aspect for Mylonite vs Conglomerate. The hardness of Mylonite is 3-4 and that of Conglomerate is 2-3. The types of Mylonite are Blastomylonites, Ultramylonites and Phyllonites whereas types of Conglomerate are Orthoconglomerate and Paraconglomerate. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mylonite and Conglomerate is white. The specific heat capacity of Mylonite is 1.50 kJ/Kg K and that of Conglomerate 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 Conglomerate is heat resistant.
