Definition
Pantellerite is a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone

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.
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

All about Pantellerite and Basanite Properties
Know all about Pantellerite and Basanite properties here. All properties of rocks are important as they define the type of rock and its application. Pantellerite and Basanite belong to Igneous Rocks.Texture of Pantellerite is Eutaxitic whereas that of Basanite is Aphanitic to Porphyritic. Pantellerite appears Layered and Foliated and Basanite appears Glassy or Pearly. The luster of Pantellerite is earthy while that of Basanite is waxy and dull. Pantellerite is available in dark greenish - grey colors whereas Basanite is available in black, brown, green, grey, red, white colors. The commercial uses of Pantellerite are creating artwork and that of Basanite are as a touchstone, creating artwork, gemstone, in fire-starting tools, manufacture of tools, metallurgical flux, jewelry, to ignite fire, used in flintlock firearms.
