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.
Trachyandesite 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.

More about Travertine and Trachyandesite
Here you can know more about Travertine and Trachyandesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Travertine and Trachyandesite consists of mineral content and compound content. The mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Trachyandesite includes Alkali feldspar, Biotite, Olivine, Plagioclase, Pyroxene, Sodic plagioclase. You can also check out the list of all Sedimentary Rocks. When we have to compare Travertine vs Trachyandesite, the texture, color and appearance plays an important role in determining the type of rock. Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors whereas, Trachyandesite is available in black, brown, light to dark grey colors. Appearance of Travertine is Fibrous and that of Trachyandesite is Dull and Soft. Properties of rock is another aspect for Travertine vs Trachyandesite. The hardness of Travertine is 3-4 and that of Trachyandesite is 4-5. The types of Travertine are Not Available whereas types of Trachyandesite are Basaltic Trachyandesite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Travertine is white while that of Trachyandesite is light to dark brown. The specific heat capacity of Travertine is 1.09 kJ/Kg K and that of Trachyandesite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Travertine is impact resistant, pressure resistant, wear resistant whereas Trachyandesite is heat resistant, pressure resistant, wear resistant.
