Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
  
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.

Laterite 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. Laterite vs Banded iron formation characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Laterite and Properties of Banded iron formation. Learn more about Laterite vs Banded iron formation in the next section. The interior uses of Laterite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Banded iron formation include Decorative aggregates and Homes. Due to some exceptional properties of Laterite and Banded iron formation, they have various applications in construction industry. The uses of Laterite in construction industry include Cobblestones, For road aggregate, Landscaping, Roadstone and that of Banded iron formation include As dimension stone, Used for flooring, stair treads, borders and window sills..
More about Laterite and Banded iron formation
Here you can know more about Laterite 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 Laterite and Banded iron formation consists of mineral content and compound content. The mineral content of Laterite includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, Plagioclase, Pyroxene 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 Laterite vs Banded iron formation, the texture, color and appearance plays an important role in determining the type of rock. Laterite is available in brown, buff, red colors whereas, Banded iron formation is available in red, reddish brown colors. Appearance of Laterite is Rough and Banded and that of Banded iron formation is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Laterite vs Banded iron formation. The hardness of Laterite is 2 and that of Banded iron formation is 5.5-6. The types of Laterite are Not Available 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 Laterite and Banded iron formation is white. The specific heat capacity of Laterite is Not Available 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.Laterite is heat resistant, pressure resistant whereas Banded iron formation is heat resistant, impact resistant, pressure resistant, wear resistant.
