Formation
Harzburgite 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 Harzburgite and Travertine
Here you can know more about Harzburgite and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Harzburgite and Travertine consists of mineral content and compound content. The mineral content of Harzburgite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, 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 Harzburgite vs Travertine, the texture, color and appearance plays an important role in determining the type of rock. Harzburgite is available in dark greenish - grey colors whereas, Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. Appearance of Harzburgite is Rough and Shiny and that of Travertine is Fibrous. Properties of rock is another aspect for Harzburgite vs Travertine. The hardness of Harzburgite is 5.5-6 and that of Travertine is 3-4. The types of Harzburgite are Ultramafic 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 Harzburgite and Travertine is white. The specific heat capacity of Harzburgite is 1.25 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.Harzburgite is heat resistant, pressure resistant, wear resistant whereas Travertine is impact resistant, pressure resistant, wear resistant.
