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 Foidolite Properties
Know all about Pantellerite and Foidolite properties here. All properties of rocks are important as they define the type of rock and its application. Pantellerite and Foidolite belong to Igneous Rocks.Texture of Pantellerite is Eutaxitic whereas that of Foidolite is Earthy. Pantellerite appears Layered and Foliated and Foidolite appears Dull. The luster of Pantellerite is earthy while that of Foidolite is subvitreous to dull. Pantellerite is available in dark greenish - grey colors whereas Foidolite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Pantellerite are creating artwork and that of Foidolite are cemetery markers, commemorative tablets, creating artwork.
