Archaeological Significance
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.
Jasperoid is a rare and peculiar type of metasomatic alteration of rocks. It is formed by extreme alteration of wall rocks within a shear zone which may occur in sediments, andesites, trachytes and basalts.

All about Pantellerite and Jasperoid Properties
Know all about Pantellerite and Jasperoid properties here. All properties of rocks are important as they define the type of rock and its application. Pantellerite belongs to Igneous Rocks while Jasperoid belongs to Sedimentary Rocks.Texture of Pantellerite is Eutaxitic whereas that of Jasperoid is Earthy. Pantellerite appears Layered and Foliated and Jasperoid appears Glassy or Pearly. The luster of Pantellerite is earthy while that of Jasperoid is vitreous and pearly. Pantellerite is available in dark greenish - grey colors whereas Jasperoid is available in black, brown, green, grey, pink, white colors. The commercial uses of Pantellerite are creating artwork and that of Jasperoid are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
