Definition
Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters
Mylonite is a metamorphic rock formed by ductile deformation during intense shearing encountered during folding and faulting, a process termed cataclastic or dynamic metamorphism

Formation
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.
Mylonites are ductilely deformed rocks formed by the accumulation of large shear strain, in ductile fault zones.

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