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