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
Adamellite is a coarse-grained porphyritic igneous rock, a variety of Monzogranite and dominated by phenocrysts of orthoclase in a granular groundmass of perthite, plagioclase and quartz

Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

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