Formation

Formation

Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.
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.

Eclogite 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 Eclogite and Travertine Reserves. Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature. 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 Eclogite vs Travertine information and Eclogite vs Travertine characteristics in the upcoming sections.

Eclogite 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. Eclogite vs Travertine characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Eclogite and Properties of Travertine. Learn more about Eclogite vs Travertine in the next section. The interior uses of Eclogite include Decorative aggregates and Interior decoration whereas the interior uses of Travertine include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Eclogite and Travertine, they have various applications in construction industry. The uses of Eclogite in construction industry include 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 Eclogite and Travertine

Here you can know more about Eclogite and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Travertine consists of mineral content and compound content. The mineral content of Eclogite includes Amphibole, Coesite, Corundum, Dolomite, Garnet, Kyanite, Lawsonite, Paragonite, Phengite, Pyroxene, Quartz, Rutile, Zoisite and mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Eclogite vs Travertine, the texture, color and appearance plays an important role in determining the type of rock. Eclogite is available in black, brown, green, grey, pink, white colors whereas, Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Travertine is Fibrous. Properties of rock is another aspect for Eclogite vs Travertine. The hardness of Eclogite is 3.5-4 and that of Travertine is 3-4. The types of Eclogite are Eclogite 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 Eclogite and Travertine is white. The specific heat capacity of Eclogite is 0.75 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.Eclogite is heat resistant whereas Travertine is impact resistant, pressure resistant, wear resistant.
