Formation

Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

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.

More about Conglomerate and Banded iron formation

Here you can know more about Conglomerate 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 Conglomerate and Banded iron formation consists of mineral content and compound content. The mineral content of Conglomerate includes Clay, Sand, Silica, Silt 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 Conglomerate vs Banded iron formation, the texture, color and appearance plays an important role in determining the type of rock. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas, Banded iron formation is available in red, reddish brown colors. Appearance of Conglomerate is Shiny and Rounded and that of Banded iron formation is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Conglomerate vs Banded iron formation. The hardness of Conglomerate is 2-3 and that of Banded iron formation is 5.5-6. The types of Conglomerate are Orthoconglomerate and Paraconglomerate 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 Conglomerate and Banded iron formation is white. The specific heat capacity of Conglomerate is 0.92 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.Conglomerate is heat resistant whereas Banded iron formation is heat resistant, impact resistant, pressure resistant, wear resistant.
