Definition
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
Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters

Formation
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.
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.

More about Shoshonite and Travertine
Here you can know more about Shoshonite and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shoshonite and Travertine consists of mineral content and compound content. The mineral content of Shoshonite includes Pyroxene and mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Shoshonite vs Travertine, the texture, color and appearance plays an important role in determining the type of rock. Shoshonite is available in brown- black, dark brown colors whereas, Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. Appearance of Shoshonite is Dull and that of Travertine is Fibrous. Properties of rock is another aspect for Shoshonite vs Travertine. The hardness of Shoshonite is 6 and that of Travertine is 3-4. The types of Shoshonite are Intermediate volcanic rock whereas types of Travertine are Thermal Travertine and Tufa. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Shoshonite is white to grey while that of Travertine is white. The specific heat capacity of Shoshonite is 0.79 kJ/Kg K and that of Travertine is 1.09 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Shoshonite is heat resistant, pressure resistant whereas Travertine is impact resistant, pressure resistant, wear resistant.
