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.
Pantellerite 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 Pantellerite Properties
Know all about Anthracite and Pantellerite properties here. All properties of rocks are important as they define the type of rock and its application. Anthracite belongs to Metamorphic Rocks while Pantellerite belongs to Igneous Rocks.Texture of Anthracite is Amorphous, Glassy whereas that of Pantellerite is Eutaxitic. Anthracite appears Veined or Pebbled and Pantellerite appears Layered and Foliated. The luster of Anthracite is shiny while that of Pantellerite is earthy. Anthracite is available in black, brown, dark brown, grey, light to dark grey colors whereas Pantellerite is available in dark greenish - grey 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 Pantellerite are creating artwork.
