Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed 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 Metapelite and Travertine Properties
Know all about Metapelite and Travertine properties here. All properties of rocks are important as they define the type of rock and its application. Metapelite belongs to Metamorphic Rocks while Travertine belongs to Sedimentary Rocks.Texture of Metapelite is Foliated whereas that of Travertine is Banded. Metapelite appears Banded and Travertine appears Fibrous. The luster of Metapelite is earthy while that of Travertine is dull to pearly. Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors whereas Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. The commercial uses of Metapelite are commemorative tablets, creating artwork and that of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery.
