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.
Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.

All about Travertine and Anthracite Properties
Know all about Travertine and Anthracite properties here. All properties of rocks are important as they define the type of rock and its application. Travertine belongs to Sedimentary Rocks while Anthracite belongs to Metamorphic Rocks.Texture of Travertine is Banded whereas that of Anthracite is Amorphous, Glassy. Travertine appears Fibrous and Anthracite appears Veined or Pebbled. The luster of Travertine is dull to pearly while that of Anthracite is shiny. Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors whereas Anthracite is available in black, brown, dark brown, grey, light to dark grey colors. The commercial uses of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery and that of Anthracite are alumina refineries, electricity generation, liquid fuel, manufacture of soap, solvents, dyes, plastics and fibres, paper industry.
