Formation
Pyroxenites are ultramafic igneous rocks which are made up of minerals of the pyroxene group, such as augite and diopside, hypersthene, bronzite or enstatite.
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

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