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
Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters

Formation
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.
Travertine is a type of sedimentary rock formed when a river carries or transports pieces of broken rock which then undergo sedimentation. They are then subjected to high temperature and pressure hence forming travertine rock.

All about Mylonite and Travertine Properties
Know all about Mylonite and Travertine properties here. All properties of rocks are important as they define the type of rock and its application. Mylonite belongs to Metamorphic Rocks while Travertine belongs to Sedimentary Rocks.Texture of Mylonite is Foliated whereas that of Travertine is Banded. Mylonite appears Dull, Banded and Foilated and Travertine appears Fibrous. The luster of Mylonite is shiny while that of Travertine is dull to pearly. Mylonite is available in black to grey colors whereas Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. The commercial uses of Mylonite are creating artwork, gemstone, jewelry and that of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery.
