Definition
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix
Mylonite is a metamorphic rock formed by ductile deformation during intense shearing encountered during folding and faulting, a process termed cataclastic or dynamic metamorphism

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

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