1 Definition

1.1 Definition

Pyrolite is an igneous rock consisting of about three parts of peridotite and one part of 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

5 Formation

5.1 Formation

Pyrolite 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 Pyrolite and Boninite Properties

Know all about Pyrolite and Boninite properties here. All properties of rocks are important as they define the type of rock and its application. Pyrolite and Boninite belong to Igneous Rocks.Texture of Pyrolite is Phaneritic whereas that of Boninite is Aphanitic to Porphyritic. Pyrolite appears Rough and Shiny and Boninite appears Dull and Soft. The luster of Pyrolite is shiny while that of Boninite is vitreous. Pyrolite is available in dark greenish - grey colors whereas Boninite is available in bluish - grey, brown, colourless, green, grey colors. The commercial uses of Pyrolite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds and that of Boninite are an oil and gas reservoir, cemetery markers, creating artwork, soil conditioner, source of magnesia (mgo).
