Definition
Teschenite is coarse- to fine-grained, dark-coloured intrusive igneous rock that usually occurs in sills, dikes and irregular masses and is always altered to some extent
Anthracite is a type of sedimentary rock which is hard and is variety of coal that has high luster

Formation
Teschenite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
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 Teschenite and Anthracite Properties
Know all about Teschenite and Anthracite properties here. All properties of rocks are important as they define the type of rock and its application. Teschenite belongs to Igneous Rocks while Anthracite belongs to Metamorphic Rocks.Texture of Teschenite is Phaneritic whereas that of Anthracite is Amorphous, Glassy. Teschenite appears Veined and Shiny and Anthracite appears Veined or Pebbled. The luster of Teschenite is not available while that of Anthracite is shiny. Teschenite is available in dark grey to black colors whereas Anthracite is available in black, brown, dark brown, grey, light to dark grey colors. The commercial uses of Teschenite are cemetery markers, commemorative tablets, creating artwork, laboratory bench tops, jewelry, sea defence, tombstones and that of Anthracite are alumina refineries, electricity generation, liquid fuel, manufacture of soap, solvents, dyes, plastics and fibres, paper industry.
