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.
Pyrolite 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 vs Pyrolite 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. Travertine vs Pyrolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Travertine and Properties of Pyrolite. Learn more about Travertine vs Pyrolite in the next section. The interior uses of Travertine include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Pyrolite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Travertine and Pyrolite, they have various applications in construction industry. The uses of Travertine in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Raw material for the manufacture of mortar and that of Pyrolite include As dimension stone, Cobblestones.
More about Travertine and Pyrolite
Here you can know more about Travertine and Pyrolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Travertine and Pyrolite consists of mineral content and compound content. The mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Pyrolite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Travertine vs Pyrolite, 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, Pyrolite is available in dark greenish - grey colors. Appearance of Travertine is Fibrous and that of Pyrolite is Rough and Shiny. Properties of rock is another aspect for Travertine vs Pyrolite. The hardness of Travertine is 3-4 and that of Pyrolite is 5.5-6. The types of Travertine are Not Available whereas types of Pyrolite are Dunite, Wehrlite, Harzburgite, Lherzolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Travertine and Pyrolite is white. The specific heat capacity of Travertine is 1.09 kJ/Kg K and that of Pyrolite is 1.25 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 Pyrolite is heat resistant, pressure resistant, wear resistant.
