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.
The banded iron layers are formed in sea water when oxygen is released by photosynthetic cyano-bacteria. The oxygen then combines with dissolved iron in ocean to form insoluble iron oxides, which precipitated out, forming a thin layer of banded iron formation on ocean floor.

Travertine vs Banded iron formation 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 Banded iron formation characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Travertine and Properties of Banded iron formation. Learn more about Travertine vs Banded iron formation in the next section. The interior uses of Travertine include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Banded iron formation include Decorative aggregates and Homes. Due to some exceptional properties of Travertine and Banded iron formation, 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 Banded iron formation include As dimension stone, Used for flooring, stair treads, borders and window sills..
More about Travertine and Banded iron formation
Here you can know more about Travertine and Banded iron formation. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Travertine and Banded iron formation consists of mineral content and compound content. The mineral content of Travertine includes Calcite, Clay, Feldspar, Micas, Quartz and mineral content of Banded iron formation includes Hematite, Magnetite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Travertine vs Banded iron formation, 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, Banded iron formation is available in red, reddish brown colors. Appearance of Travertine is Fibrous and that of Banded iron formation is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Travertine vs Banded iron formation. The hardness of Travertine is 3-4 and that of Banded iron formation is 5.5-6. The types of Travertine are Thermal Travertine and Tufa whereas types of Banded iron formation are Algoma-type , Lake Superior-type, Superior-type and Taconite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Travertine and Banded iron formation is white. The specific heat capacity of Travertine is 1.09 kJ/Kg K and that of Banded iron formation is 3.20 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 Banded iron formation is heat resistant, impact resistant, pressure resistant, wear resistant.
