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

Formation
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.
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.

All about Anthracite and Teschenite Properties
Know all about Anthracite and Teschenite properties here. All properties of rocks are important as they define the type of rock and its application. Anthracite belongs to Metamorphic Rocks while Teschenite belongs to Igneous Rocks.Texture of Anthracite is Amorphous, Glassy whereas that of Teschenite is Phaneritic. Anthracite appears Veined or Pebbled and Teschenite appears Veined and Shiny. The luster of Anthracite is shiny while that of Teschenite is not available. Anthracite is available in black, brown, dark brown, grey, light to dark grey colors whereas Teschenite is available in dark grey to black colors. The commercial uses of Anthracite are alumina refineries, electricity generation, liquid fuel, manufacture of soap, solvents, dyes, plastics and fibres, paper industry and that of Teschenite are cemetery markers, commemorative tablets, creating artwork, laboratory bench tops, jewelry, sea defence, tombstones.
