Definition
Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters
Troctolite is a mafic intrusive rock type. It consists essentially of major but variable amounts of olivine and calcic plagioclase along with minor pyroxene. It is an olivine-rich anorthosite, or a pyroxene-depleted relative of gabbro

Formation
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.
Troctolite 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 Travertine and Troctolite Properties
Know all about Travertine and Troctolite properties here. All properties of rocks are important as they define the type of rock and its application. Travertine belongs to Sedimentary Rocks while Troctolite belongs to Igneous Rocks.Texture of Travertine is Banded whereas that of Troctolite is Phaneritic. Travertine appears Fibrous and Troctolite appears Veined and Shiny. The luster of Travertine is dull to pearly while that of Troctolite is not available. Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors whereas Troctolite is available in dark grey to black colors. The commercial uses of Travertine are cemetery markers, creating artwork, gemstone, jewelry, paper industry, pottery and that of Troctolite are cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones.
