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.
Pegmatite rock is holocrystalline, intrusive igneous rock which is formed by partial melting and dewatering during the process of metamorphism.

All about Pantellerite and Pegmatite Properties
Know all about Pantellerite and Pegmatite properties here. All properties of rocks are important as they define the type of rock and its application. Pantellerite and Pegmatite belong to Igneous Rocks.Texture of Pantellerite is Eutaxitic whereas that of Pegmatite is Pegmatitic. Pantellerite appears Layered and Foliated and Pegmatite appears Layered, Banded, Veined and Shiny. The luster of Pantellerite is earthy while that of Pegmatite is grainy, pearly and vitreous. Pantellerite is available in dark greenish - grey colors whereas Pegmatite is available in black, brown, cream, green, grey, pink, red, rust, silver, white, yellow colors. The commercial uses of Pantellerite are creating artwork and that of Pegmatite are creating artwork, jewelry, source of corundum, tourmalines, beryls and topaz.
