Formation

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.  
Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

Banded iron formation vs Diamictite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Banded iron formation and Diamictite Reserves. Banded iron formation are distinctive units of sedimentary rock that are almost always of Precambrian age. Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Banded iron formation vs Diamictite information and Banded iron formation vs Diamictite characteristics in the upcoming sections.

More about Banded iron formation and Diamictite

Here you can know more about Banded iron formation and Diamictite. 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 Diamictite consists of mineral content and compound content. The mineral content of Banded iron formation includes Hematite, Magnetite, Quartz and mineral content of Diamictite includes Calcite, Clay, Feldspar, Micas, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Banded iron formation vs Diamictite, 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, Diamictite is available in brown, buff colors. Appearance of Banded iron formation is Layered, Banded, Veined and Shiny and that of Diamictite is Banded. Properties of rock is another aspect for Banded iron formation vs Diamictite. The hardness of Banded iron formation is 5.5-6 and that of Diamictite is 2-3. The types of Banded iron formation are Algoma-type , Lake Superior-type, Superior-type and Taconite whereas types of Diamictite are Bedded Diamictite and Laminated Diamictite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Banded iron formation is white while that of Diamictite is light to dark brown. The specific heat capacity of Banded iron formation is 3.20 kJ/Kg K and that of Diamictite is 0.75 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 Diamictite is heat resistant, impact resistant.
