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

Etymology
From Greek mulōn mill + -ite
From Latin conglomeratus, to roll together, i.e. from com together + glomerare to gather into a ball, from glomus (genitive glomeris) a ball

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.

All about Mylonite and Conglomerate Properties
Know all about Mylonite and Conglomerate properties here. All properties of rocks are important as they define the type of rock and its application. Mylonite belongs to Metamorphic Rocks while Conglomerate belongs to Sedimentary Rocks.Texture of Mylonite is Foliated whereas that of Conglomerate is Clastic. Mylonite appears Dull, Banded and Foilated and Conglomerate appears Shiny and Rounded. The luster of Mylonite is shiny while that of Conglomerate is dull. 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. The commercial uses of Mylonite are creating artwork, gemstone, jewelry and that of Conglomerate are cemetery markers, in aquifers, tombstones.
