Definition
Gabbro is an intrusive igneous rock which is chemically equivalent to plutonic Basalt
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

Archaeological Significance
Formation
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

All about Gabbro and Boninite Properties
Know all about Gabbro and Boninite properties here. All properties of rocks are important as they define the type of rock and its application. Gabbro and Boninite belong to Igneous Rocks.Texture of Gabbro is Phaneritic whereas that of Boninite is Aphanitic to Porphyritic. Gabbro appears Veined and Shiny and Boninite appears Dull and Soft. The luster of Gabbro is while that of Boninite is vitreous. Gabbro is available in dark grey to black colors whereas Boninite is available in bluish - grey, brown, green, grey colors. The commercial uses of Gabbro are cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones and that of Boninite are an oil and gas reservoir, cemetery markers, creating artwork, soil conditioner, source of magnesia (mgo).
