Formation
Pantellerite 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 Pantellerite and Picrite Properties
Know all about Pantellerite and Picrite properties here. All properties of rocks are important as they define the type of rock and its application. Pantellerite and Picrite belong to Igneous Rocks.Texture of Pantellerite is Eutaxitic whereas that of Picrite is Earthy, Rough. Pantellerite appears Layered and Foliated and Picrite appears Rough and Shiny. The luster of Pantellerite is earthy while that of Picrite is subvitreous to dull. Pantellerite is available in dark greenish - grey colors whereas Picrite is available in black, brown, colourless, green, grey, pink, white, yellow colors. The commercial uses of Pantellerite are creating artwork and that of Picrite are as a feed additive for livestock, as armour rock for sea walls, metallurgical flux, pottery, source of magnesia (mgo).
