5 Formation

5.1 Formation

Coal forms from the accumulation of plant debris in a swamp environment which is buried by sediments such as mud or sand and then compacted to form coal.

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.

Coal 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 Coal and Travertine Reserves. Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds. 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 Coal vs Travertine information and Coal vs Travertine characteristics in the upcoming sections.

Coal 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. Coal vs Travertine characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Coal and Properties of Travertine. Learn more about Coal vs Travertine in the next section. The interior uses of Coal include Not yet used whereas the interior uses of Travertine include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Coal and Travertine, they have various applications in construction industry. The uses of Coal in construction industry include Cement manufacture, For road aggregate, Making natural cement, Steel production 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 Coal and Travertine

Here you can know more about Coal and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Coal and Travertine consists of mineral content and compound content. The mineral content of Coal includes Analcime, Apatite, Barite, Calcite, Chalcopyrite, Chlorite, Chromite, Clausthalite, Clay Minerals, Crandallite Group, Dolomite, Feldspar, Galena, Gypsum, Marcasite, Muscovite or Illite, Pyrite, Quartz, Siderite, Sphalerite, Zircon 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 Coal vs Travertine, the texture, color and appearance plays an important role in determining the type of rock. Coal is available in black, brown, dark brown, grey, light to dark grey colors whereas, Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors. Appearance of Coal is Veined or Pebbled and that of Travertine is Fibrous. Properties of rock is another aspect for Coal vs Travertine. The hardness of Coal is 1-1.5 and that of Travertine is 3-4. The types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite 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 Coal is black while that of Travertine is white. The specific heat capacity of Coal is 1.32 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.Coal is heat resistant whereas Travertine is impact resistant, pressure resistant, wear resistant.
