Formation

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.   
Pyroxenites are ultramafic igneous rocks which are made up of minerals of the pyroxene group, such as augite and diopside, hypersthene, bronzite or enstatite.

All about Monzonite and Pyroxenite Properties

Know all about Monzonite and Pyroxenite properties here. All properties of rocks are important as they define the type of rock and its application. Monzonite and Pyroxenite belong to Igneous Rocks.Texture of Monzonite is Phaneritic whereas that of Pyroxenite is Clastic, Granular, Phaneritic, Porphyritic. Monzonite appears Shiny and Pyroxenite appears Layered, Banded, Veined and Shiny. The luster of Monzonite is subvitreous to dull while that of Pyroxenite is dull to vitreous to submetallic. Monzonite is available in black, brown, light to dark grey, white colors whereas Pyroxenite is available in black to grey, bluish - grey, dark greenish - grey, green, light greenish grey colors. The commercial uses of Monzonite are creating artwork and that of Pyroxenite are cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones.
