Formation

Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.

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.

Amphibolite vs Travertine 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 Amphibolite and Travertine Reserves. Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase. Travertine is a mineral consisting of layered calcium carbonate formed by deposition from spring waters. 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 Amphibolite vs Travertine information and Amphibolite vs Travertine characteristics in the upcoming sections.

Amphibolite vs Travertine 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. Amphibolite vs Travertine characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Amphibolite and Properties of Travertine. Learn more about Amphibolite vs Travertine in the next section. The interior uses of Amphibolite include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels and Kitchens whereas the interior uses of Travertine include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Amphibolite and Travertine, they have various applications in construction industry. The uses of Amphibolite in construction industry include As dimension stone, Building houses or walls, Cobblestones, Construction aggregate, For road aggregate, Landscaping, Production of glass and ceramics, Roadstone and that of Travertine include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Raw material for the manufacture of mortar.

More about Amphibolite and Travertine

Here you can know more about Amphibolite and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Amphibolite and Travertine consists of mineral content and compound content. The mineral content of Amphibolite includes Amphibole, Andalusite, Biotite, Calcite, Epidote, Garnet, Hornblade, Kyanite, Magnetite, Olivine, Plagioclase, Pyroxene, Staurolite, Wollastonite and mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Amphibolite vs Travertine, the texture, color and appearance plays an important role in determining the type of rock. Amphibolite is available in black, brown, green, grey colors whereas, Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. Appearance of Amphibolite is Foliated and that of Travertine is Fibrous. Properties of rock is another aspect for Amphibolite vs Travertine. The hardness of Amphibolite is 6-7 and that of Travertine is 3-4. The types of Amphibolite are Hornblendite whereas types of Travertine are Thermal Travertine and Tufa. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Amphibolite is white to grey while that of Travertine is white. The specific heat capacity of Amphibolite is 0.84 kJ/Kg K and that of Travertine is 1.09 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Amphibolite is heat resistant, pressure resistant, wear resistant whereas Travertine is impact resistant, pressure resistant, wear resistant.
