Definition
A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.
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
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

All about Serpentinite and Boninite Properties
Know all about Serpentinite and Boninite properties here. All properties of rocks are important as they define the type of rock and its application. Serpentinite belongs to Metamorphic Rocks while Boninite belongs to Igneous Rocks.Texture of Serpentinite is Earthy whereas that of Boninite is Aphanitic to Porphyritic. Serpentinite appears Rough and Dull and Boninite appears Dull and Soft. The luster of Serpentinite is waxy and dull while that of Boninite is vitreous. Serpentinite is available in black, brown, green, grey, white colors whereas Boninite is available in bluish - grey, brown, green, grey colors. The commercial uses of Serpentinite are commemorative tablets, creating artwork and that of Boninite are an oil and gas reservoir, cemetery markers, creating artwork, soil conditioner, source of magnesia (mgo).
