Definition
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
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

Formation
Adamellite is a type of Igneous rock which is formed through the cooling and solidification of lava or magma and is a variety of Monzogranite.

All about Adamellite and Boninite Properties
Know all about Adamellite and Boninite properties here. All properties of rocks are important as they define the type of rock and its application. Adamellite and Boninite belong to Igneous Rocks.Texture of Adamellite is Porphyritic whereas that of Boninite is Aphanitic to Porphyritic. Adamellite appears Veined or Pebbled and Boninite appears Dull and Soft. The luster of Adamellite is dull to grainy with sporadic parts pearly and vitreous while that of Boninite is vitreous. Adamellite is available in black, grey, orange, pink, white colors whereas Boninite is available in bluish - grey, brown, colourless, green, grey colors. The commercial uses of Adamellite are curling, gemstone, laboratory bench tops, tombstones and that of Boninite are an oil and gas reservoir, cemetery markers, creating artwork, soil conditioner, source of magnesia (mgo).
