Formation
Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.
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.

Peridotite vs Travertine Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Peridotite vs Travertine characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Peridotite and Properties of Travertine. Learn more about Peridotite vs Travertine in the next section. The interior uses of Peridotite include Decorative aggregates and Interior decoration whereas the interior uses of Travertine include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Peridotite and Travertine, they have various applications in construction industry. The uses of Peridotite in construction industry include As dimension stone, Cobblestones and that of Travertine include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Raw material for the manufacture of mortar.
More about Peridotite and Travertine
Here you can know more about Peridotite and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Peridotite and Travertine consists of mineral content and compound content. The mineral content of Peridotite 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 Peridotite vs Travertine, the texture, color and appearance plays an important role in determining the type of rock. Peridotite is available in dark greenish - grey colors whereas, Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. Appearance of Peridotite is Rough and Shiny and that of Travertine is Fibrous. Properties of rock is another aspect for Peridotite vs Travertine. The hardness of Peridotite is 5.5-6 and that of Travertine is 3-4. The types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite whereas types of Travertine are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Peridotite and Travertine is white. The specific heat capacity of Peridotite is 1.26 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.Peridotite is heat resistant, pressure resistant, wear resistant whereas Travertine is impact resistant, pressure resistant, wear resistant.
