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
Granodiorite is a coarse-grained intrusive igneous rock containing quartz and plagioclase, and which has composition in between granite and diorite

Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
Granodiorite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks.

All about Boninite and Granodiorite Properties
Know all about Boninite and Granodiorite properties here. All properties of rocks are important as they define the type of rock and its application. Boninite and Granodiorite belong to Igneous Rocks.Texture of Boninite is Aphanitic to Porphyritic whereas that of Granodiorite is Granular, Phaneritic. Boninite appears Dull and Soft and Granodiorite appears Veined or Pebbled. The luster of Boninite is vitreous while that of Granodiorite is grainy, pearly and vitreous. Boninite is available in bluish - grey, brown, colourless, green, grey colors whereas Granodiorite is available in black, grey, orange, pink, white 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 Granodiorite are curling, gemstone, laboratory bench tops, tombstones.
