Formation

Formation

Shale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies. They are later compacted hence forming shale.
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.

Shale 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 Shale and Travertine Reserves. Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles. 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 Shale vs Travertine information and Shale vs Travertine characteristics in the upcoming sections.

Shale 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. Shale vs Travertine characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Shale and Properties of Travertine. Learn more about Shale vs Travertine in the next section. The interior uses of Shale include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Travertine include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Shale and Travertine, they have various applications in construction industry. The uses of Shale in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar 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 Shale and Travertine

Here you can know more about Shale and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Shale and Travertine consists of mineral content and compound content. The mineral content of Shale includes Albite, Biotite, Calcite, Chert, Chlorite, Dolomite, Hematite, Micas, Muscovite or Illite, Pyrite, Quartz, Silica, Sulfides and mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Shale vs Travertine, the texture, color and appearance plays an important role in determining the type of rock. Shale is available in black, brown, buff, green, grey, red, yellow colors whereas, Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. Appearance of Shale is Muddy and that of Travertine is Fibrous. Properties of rock is another aspect for Shale vs Travertine. The hardness of Shale is 3 and that of Travertine is 3-4. The types of Shale are Red Shale, Black Shale, Green Shale, Grey Shale and Yellow Shale whereas types of Travertine are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Shale and Travertine is white. The specific heat capacity of Shale is 0.39 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.Shale is heat resistant, impact resistant whereas Travertine is impact resistant, pressure resistant, wear resistant.
