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
Sandstone is defined as a rock which is composed of sand-sized grains of various minerals mostly of uniform size and often are smooth and rounded

Formation
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.
Sandstone is a sedimentary rock which forms from cemented sand-sized clasts. It forms when sand layers are buried under sediments of sand.

All about Mylonite and Sandstone Properties
Know all about Mylonite and Sandstone properties here. All properties of rocks are important as they define the type of rock and its application. Mylonite belongs to Metamorphic Rocks while Sandstone belongs to Sedimentary Rocks.Texture of Mylonite is Foliated whereas that of Sandstone is Clastic, Granular, Rough. Mylonite appears Dull, Banded and Foilated and Sandstone appears Rough. The luster of Mylonite is shiny while that of Sandstone is dull. Mylonite is available in black to grey colors whereas Sandstone is available in beige, black, brown, colourless, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. The commercial uses of Mylonite are creating artwork, gemstone, jewelry and that of Sandstone are an oil and gas reservoir, in aquifers, petroleum reservoirs, soil conditioner, source of magnesia (mgo), tombstones, used in aquariums.
