Definition
Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters
Shoshonite is a basaltic rock, properly a potassic trachyandesite, composed of olivine, augite and plagioclase phenocrysts in a groundmass with calcic plagioclase and sanidine and some dark-colored volcanic glass

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