5.1 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.
Rhyolite is a felsic extrusive rock and due to its high silica content, rhyolite lava is very viscous and is volcanic equivalent of granite.

Travertine vs Rhyolite 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 Rhyolite Reserves. Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters. Rhyolite is a fine-grained igneous rock which is rich in silica. 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 Rhyolite information and Travertine vs Rhyolite characteristics in the upcoming sections.

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

More about Travertine and Rhyolite

Here you can know more about Travertine and Rhyolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Travertine and Rhyolite consists of mineral content and compound content. The mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Rhyolite includes Biotite, Feldspar, Hornblade, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Travertine vs Rhyolite, 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, Rhyolite is available in grey, white, light black colors. Appearance of Travertine is Fibrous and that of Rhyolite is Banded. Properties of rock is another aspect for Travertine vs Rhyolite. The hardness of Travertine is 3-4 and that of Rhyolite is 6-7. The types of Travertine are Not Available whereas types of Rhyolite are Pumice Rocks, Obsidian Rocks, Perlite Rocks, Porphyritic Rocks.. 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 Rhyolite is colorless. The specific heat capacity of Travertine is 1.09 kJ/Kg K and that of Rhyolite 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 Rhyolite is heat resistant, wear resistant.
