Archaeological Significance
Formation
Lherzolite 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.
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 Lherzolite and Jadeitite Properties
Know all about Lherzolite and Jadeitite properties here. All properties of rocks are important as they define the type of rock and its application. Lherzolite belongs to Igneous Rocks while Jadeitite belongs to Metamorphic Rocks.Texture of Lherzolite is Grenue whereas that of Jadeitite is Earthy. Lherzolite appears Glassy, Vesicular and Foilated and Jadeitite appears Rough and Dull. The luster of Lherzolite is subvitreous to dull while that of Jadeitite is waxy and dull. Lherzolite is available in black, dark greenish - grey, green, pink, purple colors whereas Jadeitite is available in black, brown, green, grey, white colors. The commercial uses of Lherzolite are as armour rock for sea walls, source of magnesia (mgo), used in aquariums and that of Jadeitite are commemorative tablets, creating artwork, jewelry.
