Definition
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone

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