Formation
Theralite 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 Theralite and Travertine Properties
Know all about Theralite and Travertine properties here. All properties of rocks are important as they define the type of rock and its application. Theralite belongs to Igneous Rocks while Travertine belongs to Sedimentary Rocks.Texture of Theralite is Phaneritic whereas that of Travertine is Banded. Theralite appears Veined and Shiny and Travertine appears Fibrous. The luster of Theralite is waxy and dull while that of Travertine is dull to pearly. Theralite is available in dark grey to black colors whereas Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. The commercial uses of Theralite are cemetery markers, commemorative tablets, creating artwork, laboratory bench tops, jewelry, sea defence, tombstones and that of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery.
