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
  
Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of Earth

Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
  
Basalt forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.

All about Boninite and Basalt Properties
Know all about Boninite and Basalt properties here. All properties of rocks are important as they define the type of rock and its application. Boninite and Basalt belong to Igneous Rocks.Texture of Boninite is Aphanitic to Porphyritic whereas that of Basalt is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular. Boninite appears Dull and Soft and Basalt appears Dull and Soft. The luster of Boninite is vitreous while that of Basalt is not available. Boninite is available in bluish - grey, brown, colourless, green, grey colors whereas Basalt is available in black, brown, 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 Basalt are an oil and gas reservoir, commemorative tablets, creating artwork, used in aquariums.
