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.
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.

More about Travertine and Lherzolite
Here you can know more about Travertine and Lherzolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Travertine and Lherzolite consists of mineral content and compound content. The mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Lherzolite includes Harzburgite, Olivine, Pyroxene, Pyrrhotite. You can also check out the list of all . When we have to compare Travertine vs Lherzolite, 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, Lherzolite is available in black, dark greenish - grey, green, pink, purple colors. Appearance of Travertine is Fibrous and that of Lherzolite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Travertine vs Lherzolite. The hardness of Travertine is 3-4 and that of Lherzolite is 6.5. The types of Travertine are Not Available whereas types of Lherzolite are Garnet Lherzolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Travertine and Lherzolite is white. The specific heat capacity of Travertine is 1.09 kJ/Kg K and that of Lherzolite is 0.95 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 Lherzolite is heat resistant, impact resistant, pressure resistant, wear resistant.
