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.

All about Lherzolite and Pantellerite Properties
Know all about Lherzolite and Pantellerite properties here. All properties of rocks are important as they define the type of rock and its application. Lherzolite and Pantellerite belong to Igneous Rocks.Texture of Lherzolite is Grenue whereas that of Pantellerite is Eutaxitic. Lherzolite appears Glassy, Vesicular and Foilated and Pantellerite appears Layered and Foliated. The luster of Lherzolite is subvitreous to dull while that of Pantellerite is earthy. Lherzolite and Pantellerite are available in black, dark greenish - grey, green, pink, purple colors. The commercial uses of Lherzolite are as armour rock for sea walls, source of magnesia (mgo), used in aquariums and that of Pantellerite are creating artwork.
