Definition
Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction
Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds

Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
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 Boninite and Coal Properties
Know all about Boninite and Coal properties here. All properties of rocks are important as they define the type of rock and its application. Boninite belongs to Igneous Rocks while Coal belongs to Sedimentary Rocks.Texture of Boninite is Aphanitic to Porphyritic whereas that of Coal is Amorphous, Glassy. Boninite appears Dull and Soft and Coal appears Veined or Pebbled. The luster of Boninite is vitreous while that of Coal is dull to vitreous to submetallic. Boninite is available in bluish - grey, brown, colourless, green, grey colors whereas Coal is available in black, brown, dark brown, grey, light to dark grey colors. The commercial uses of Boninite are an oil and gas reservoir, cemetery markers, creating artwork, soil conditioner, source of magnesia (mgo) and that of Coal are alumina refineries, electricity generation, liquid fuel, manufacture of soap, solvents, dyes, plastics and fibres, paper industry.
