Formation
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.
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 Charnockite and Travertine Properties
Know all about Charnockite and Travertine properties here. All properties of rocks are important as they define the type of rock and its application. Charnockite belongs to Igneous Rocks while Travertine belongs to Sedimentary Rocks.Texture of Charnockite is Granular whereas that of Travertine is Banded. Charnockite appears Veined or Pebbled and Travertine appears Fibrous. The luster of Charnockite is while that of Travertine is dull to pearly. Charnockite is available in black, grey, orange, pink, white colors whereas Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. The commercial uses of Charnockite are curling, gemstone, laboratory bench tops, tombstones and that of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery.
