Formation

Formation

Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
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.

Scoria 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 Scoria and Travertine Reserves. Scoria is a dark-colored extrusive igneous rock with abundant round bubble-like cavities. 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 Scoria vs Travertine information and Scoria vs Travertine characteristics in the upcoming sections.

Scoria 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. Scoria vs Travertine characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Scoria and Properties of Travertine. Learn more about Scoria vs Travertine in the next section. The interior uses of Scoria 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 Scoria and Travertine, they have various applications in construction industry. The uses of Scoria in construction industry include Cement manufacture, Construction aggregate, For road aggregate, In landscaping and drainage works 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 Scoria and Travertine

Here you can know more about Scoria and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Scoria and Travertine consists of mineral content and compound content. The mineral content of Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica 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 Scoria vs Travertine, the texture, color and appearance plays an important role in determining the type of rock. Scoria is available in black, brown, dark grey to black, red colors whereas, Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. Appearance of Scoria is Glassy and Vesicular and that of Travertine is Fibrous. Properties of rock is another aspect for Scoria vs Travertine. The hardness of Scoria is 5-6 and that of Travertine is 3-4. The types of Scoria are Basaltic Scoria and Andesitic Scoria 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 Scoria and Travertine is white. The specific heat capacity of Scoria 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.Scoria is heat resistant, impact resistant, pressure resistant, wear resistant whereas Travertine is impact resistant, pressure resistant, wear resistant.
