Boninite and Monzonite


Monzonite and Boninite


Definition

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

Formation

Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.   
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.

All about Boninite and Monzonite Properties

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