Formation
Theralite 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 Theralite and Anthracite Properties
Know all about Theralite and Anthracite properties here. All properties of rocks are important as they define the type of rock and its application. Theralite belongs to Igneous Rocks while Anthracite belongs to Metamorphic Rocks.Texture of Theralite is Phaneritic whereas that of Anthracite is Amorphous, Glassy. Theralite appears Veined and Shiny and Anthracite appears Veined or Pebbled. The luster of Theralite is waxy and dull while that of Anthracite is shiny. Theralite 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 Theralite 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.
