Archaeological Significance
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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Jadeitite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

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