Formation
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 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 vs Coal 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. Travertine vs Coal characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Travertine and Properties of Coal. Learn more about Travertine vs Coal in the next section. The interior uses of Travertine include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Coal include Not yet used. Due to some exceptional properties of Travertine and Coal, they have various applications in construction industry. The uses of Travertine in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Raw material for the manufacture of mortar and that of Coal include Cement manufacture, For road aggregate, Making natural cement, Steel production.
More about Travertine and Coal
Here you can know more about Travertine and Coal. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Travertine and Coal consists of mineral content and compound content. The mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, Quartz and 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. You can also check out the list of all Sedimentary Rocks. When we have to compare Travertine vs Coal, the texture, color and appearance plays an important role in determining the type of rock. Travertine is available in beige, black, blue, brown, grey, red, white, yellow colors whereas, Coal is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Travertine is Fibrous and that of Coal is Veined or Pebbled. Properties of rock is another aspect for Travertine vs Coal. The hardness of Travertine is 3-4 and that of Coal is 1-1.5. The types of Travertine are Not Available whereas types of Coal are Peat, Lignite, Sub-Bituminous Coal, Bituminous Coal, Anthracite, Graphite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Travertine is white while that of Coal is black. The specific heat capacity of Travertine is 1.09 kJ/Kg K and that of Coal is 1.32 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Travertine is impact resistant, pressure resistant, wear resistant whereas Coal is heat resistant.
