5 Formation

5.1 Formation

Coal formation takes place due to accumulation of plant debris in a swamp environment. The Coal formation process continues, as peat turns into lignite brown or black coal at increasing heat 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.

Lignite 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 Lignite and Travertine Reserves. Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. 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 Lignite vs Travertine information and Lignite vs Travertine characteristics in the upcoming sections.

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

Here you can know more about Lignite and Travertine. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Travertine consists of mineral content and compound content. The mineral content of Lignite is not available 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 Lignite vs Travertine, the texture, color and appearance plays an important role in determining the type of rock. Lignite 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 Lignite is Veined or Pebbled and that of Travertine is Fibrous. Properties of rock is another aspect for Lignite vs Travertine. The hardness of Lignite is 1 and that of Travertine is 3-4. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite 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 Lignite is black while that of Travertine is white. The specific heat capacity of Lignite is 1.26 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.Lignite is heat resistant whereas Travertine is impact resistant, pressure resistant, wear resistant.
