Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
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 Basanite and Anthracite Properties
Know all about Basanite and Anthracite properties here. All properties of rocks are important as they define the type of rock and its application. Basanite belongs to Igneous Rocks while Anthracite belongs to Metamorphic Rocks.Texture of Basanite is Aphanitic to Porphyritic whereas that of Anthracite is Amorphous, Glassy. Basanite appears Glassy or Pearly and Anthracite appears Veined or Pebbled. The luster of Basanite is waxy and dull while that of Anthracite is shiny. Basanite is available in black, brown, green, grey, red, white colors whereas Anthracite is available in black, brown, dark brown, grey, light to dark grey colors. The commercial uses of Basanite are as a touchstone, creating artwork, gemstone, in fire-starting tools, manufacture of tools, metallurgical flux, jewelry, to ignite fire, used in flintlock firearms and that of Anthracite are alumina refineries, electricity generation, liquid fuel, manufacture of soap, solvents, dyes, plastics and fibres, paper industry.
