Definition
Cataclasite is a type of cataclastic rock that is formed by fracturing and comminution during faulting. It is normally cohesive and non-foliated, consisting of angular clasts in a finer-grained matrix
Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters

Formation
Cataclasiste rocks mainly form by pressure deep under the Earth's surface, from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
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 Cataclasite and Travertine Properties
Know all about Cataclasite and Travertine properties here. All properties of rocks are important as they define the type of rock and its application. Cataclasite belongs to Metamorphic Rocks while Travertine belongs to Sedimentary Rocks.Texture of Cataclasite is Clastic whereas that of Travertine is Banded. Cataclasite appears Dull and Banded and Travertine appears Fibrous. The luster of Cataclasite is vitreous while that of Travertine is dull to pearly. Cataclasite is available in brown, green, white, yellow colors whereas Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. The commercial uses of Cataclasite are commemorative tablets, creating artwork and that of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery.
