Basanite and Coal
Definition
Definition
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone
Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds

Formation
Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Coal forms from the accumulation of plant debris in a swamp environment which is buried by sediments such as mud or sand and then compacted to form coal.

All about Basanite and Coal Properties
Know all about Basanite and Coal properties here. All properties of rocks are important as they define the type of rock and its application. Basanite belongs to Igneous Rocks while Coal belongs to Sedimentary Rocks.Texture of Basanite is Aphanitic to Porphyritic whereas that of Coal is Amorphous, Glassy. Basanite appears Glassy or Pearly and Coal appears Veined or Pebbled. The luster of Basanite is waxy and dull while that of Coal is dull to vitreous to submetallic. Basanite is available in black, brown, green, grey, red, white colors whereas Coal 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 Coal are alumina refineries, electricity generation, liquid fuel, manufacture of soap, solvents, dyes, plastics and fibres, paper industry.
