Formation

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.   
Pyroxenites are ultramafic igneous rocks which are made up of minerals of the pyroxene group, such as augite and diopside, hypersthene, bronzite or enstatite.

Travertine vs Pyroxenite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Travertine and Pyroxenite Reserves. Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters. Pyroxenite is a dark, greenish, granular intrusive igneous rock consisting mainly of pyroxenes and olivine. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Travertine vs Pyroxenite information and Travertine vs Pyroxenite characteristics in the upcoming sections.

Travertine vs Pyroxenite 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 Pyroxenite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Travertine and Properties of Pyroxenite. Learn more about Travertine vs Pyroxenite in the next section. The interior uses of Travertine include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Pyroxenite include Countertops, Decorative aggregates, Interior decoration and Kitchens. Due to some exceptional properties of Travertine and Pyroxenite, 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 Pyroxenite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.

More about Travertine and Pyroxenite

Here you can know more about Travertine and Pyroxenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Travertine and Pyroxenite consists of mineral content and compound content. The mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Pyroxenite includes Amphibole, Augite, Bronzite, Chromite, Diopside, Enstatite, Garnet, Hornblende, Hypersthene, Magnetite, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Travertine vs Pyroxenite, 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, Pyroxenite is available in black to grey, bluish - grey, dark greenish - grey, green, light greenish grey colors. Appearance of Travertine is Fibrous and that of Pyroxenite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Travertine vs Pyroxenite. The hardness of Travertine is 3-4 and that of Pyroxenite is 7. The types of Travertine are Not Available whereas types of Pyroxenite are Clinopyroxenites, Orthopyroxenites and Websterites. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Travertine is white while that of Pyroxenite is white, greenish white or grey. The specific heat capacity of Travertine is 1.09 kJ/Kg K and that of Pyroxenite is Not Available. 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 Pyroxenite is impact resistant, pressure resistant, wear resistant.
