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.
Rhyodacite 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 Rhyodacite 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 Rhyodacite Reserves. Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters. Rhyodacite is an extrusive volcanic rock intermediate in composition between dacite and rhyolite. 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 Rhyodacite information and Travertine vs Rhyodacite characteristics in the upcoming sections.

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

More about Travertine and Rhyodacite

Here you can know more about Travertine and Rhyodacite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Travertine and Rhyodacite consists of mineral content and compound content. The mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Rhyodacite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Travertine vs Rhyodacite, 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, Rhyodacite is available in black to grey, dark greenish - grey colors. Appearance of Travertine is Fibrous and that of Rhyodacite is Skeletal. Properties of rock is another aspect for Travertine vs Rhyodacite. The hardness of Travertine is 3-4 and that of Rhyodacite is 5.5-6. The types of Travertine are Thermal Travertine and Tufa whereas types of Rhyodacite are Intermediate volcanic rock. 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 Rhyodacite is black. The specific heat capacity of Travertine is 1.09 kJ/Kg K and that of Rhyodacite is 1.12 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 Rhyodacite is heat resistant.
