Formation
Lherzolite 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.

Lherzolite 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. Lherzolite vs Travertine characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lherzolite and Properties of Travertine. Learn more about Lherzolite vs Travertine in the next section. The interior uses of Lherzolite include Decorative aggregates, Entryways, Homes and Interior decoration whereas the interior uses of Travertine include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Lherzolite and Travertine, they have various applications in construction industry. The uses of Lherzolite in construction industry include Landscaping, Manufacture of magnesium and dolomite refractories, Used for flooring, stair treads, borders and window sills. 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 Lherzolite and Travertine
Here you can know more about Lherzolite and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lherzolite and Travertine consists of mineral content and compound content. The mineral content of Lherzolite includes Harzburgite, Olivine, Pyroxene, Pyrrhotite 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 Lherzolite vs Travertine, the texture, color and appearance plays an important role in determining the type of rock. Lherzolite is available in black, dark greenish - grey, green, pink, purple colors whereas, Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. Appearance of Lherzolite is Glassy, Vesicular and Foilated and that of Travertine is Fibrous. Properties of rock is another aspect for Lherzolite vs Travertine. The hardness of Lherzolite is 6.5 and that of Travertine is 3-4. The types of Lherzolite are Garnet Lherzolite 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 Lherzolite and Travertine is white. The specific heat capacity of Lherzolite is 0.95 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.Lherzolite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Travertine is impact resistant, pressure resistant, wear resistant.
