Formation

Formation

Oil Shale forms on the beds of seas and lakes and its formation starts with the organic debris settling and accumulating at the bottom of a lake or sea which are then transformed into rock with the help of high temperature and pressure.
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.

Oil 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 Oil shale and Travertine Reserves. Oil Shale is a fine-grained sedimentary rock from which oil is extracted. 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 Oil shale vs Travertine information and Oil shale vs Travertine characteristics in the upcoming sections.

Oil 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. Oil shale vs Travertine characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Oil shale and Properties of Travertine. Learn more about Oil shale vs Travertine in the next section. The interior uses of Oil shale include whereas the interior uses of Travertine include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Oil shale and Travertine, they have various applications in construction industry. The uses of Oil shale in construction industry include Cement manufacture, Construction aggregate, For road aggregate, Serves as an oil and gas reservoir rock 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 Oil shale and Travertine

Here you can know more about Oil shale and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Oil shale and Travertine consists of mineral content and compound content. The mineral content of Oil 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 Oil shale vs Travertine, the texture, color and appearance plays an important role in determining the type of rock. Oil 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 Oil shale is Muddy and that of Travertine is Fibrous. Properties of rock is another aspect for Oil shale vs Travertine. The hardness of Oil shale is 2-3 and that of Travertine is 3-4. The types of Oil shale are Carbonate-rich Shale, Siliceous Shale and Cannel Shale 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 Oil shale and Travertine is white. The specific heat capacity of Oil 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.Oil shale is heat resistant, impact resistant whereas Travertine is impact resistant, pressure resistant, wear resistant.
