Formation
Icelandite 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 Icelandite and Travertine Properties
Know all about Icelandite and Travertine properties here. All properties of rocks are important as they define the type of rock and its application. Icelandite belongs to Igneous Rocks while Travertine belongs to Sedimentary Rocks.Texture of Icelandite is Aphanitic to Porphyritic whereas that of Travertine is Banded. Icelandite appears Dull and Soft and Travertine appears Fibrous. The luster of Icelandite is vitreous while that of Travertine is dull to pearly. Icelandite is available in bluish - grey, grey, pink, yellow colors whereas Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. The commercial uses of Icelandite are cemetery markers, creating artwork and that of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery.
