Definition

Monzonite is a granular igneous rock with composition between syenite and diorite and containing approximately equal amounts of orthoclase and plagioclase

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

Monzonite 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 Monzonite and Boninite Properties

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