Formation
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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Talc Carbonate is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Also you can check about Properties of Banded iron formation and Properties of Talc carbonate. Learn more about Banded iron formation vs Talc carbonate in the next section. The interior uses of Banded iron formation include Decorative aggregates and Homes whereas the interior uses of Talc carbonate include Decorative aggregates and Interior decoration. Due to some exceptional properties of Banded iron formation and Talc carbonate, they have various applications in construction industry. The uses of Banded iron formation in construction industry include As dimension stone, Used for flooring, stair treads, borders and window sills. and that of Talc carbonate include Source of calcium.
More about Banded iron formation and Talc carbonate
Here you can know more about Banded iron formation and Talc carbonate. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Banded iron formation and Talc carbonate consists of mineral content and compound content. The mineral content of Banded iron formation includes Hematite, Magnetite, Quartz and mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium. You can also check out the list of all Sedimentary Rocks. When we have to compare Banded iron formation vs Talc carbonate, the texture, color and appearance plays an important role in determining the type of rock. Banded iron formation is available in red, reddish brown colors whereas, Talc carbonate is available in colourless, grey, white colors. Appearance of Banded iron formation is Layered, Banded, Veined and Shiny and that of Talc carbonate is Soft. Properties of rock is another aspect for Banded iron formation vs Talc carbonate. The hardness of Banded iron formation is 5.5-6 and that of Talc carbonate is 1-2. The types of Banded iron formation are Algoma-type , Lake Superior-type, Superior-type and Taconite whereas types of Talc carbonate are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Banded iron formation and Talc carbonate is white. The specific heat capacity of Banded iron formation is 3.20 kJ/Kg K and that of Talc carbonate is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Banded iron formation is heat resistant, impact resistant, pressure resistant, wear resistant whereas Talc carbonate is heat resistant, wear resistant.
