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.
Travertine is a type of sedimentary rock formed when a river carries or transports pieces of broken rock which then undergo sedimentation. They are then subjected to high temperature and pressure hence forming travertine rock.

All about Pantellerite and Travertine Properties
Know all about Pantellerite and Travertine properties here. All properties of rocks are important as they define the type of rock and its application. Pantellerite belongs to Igneous Rocks while Travertine belongs to Sedimentary Rocks.Texture of Pantellerite is Eutaxitic whereas that of Travertine is Banded. Pantellerite appears Layered and Foliated and Travertine appears Fibrous. The luster of Pantellerite is earthy while that of Travertine is dull to pearly. Pantellerite is available in dark greenish - grey colors whereas Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. The commercial uses of Pantellerite are creating artwork and that of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery.
