Definition
Foidolite is a rare type of coarse-grained intrusive igneous rock with a feldspathoid mineral content greater than 60%
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
Foidolites is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

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