Formation

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

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 Serpentinite and Banded iron formation

Here you can know more about Serpentinite 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 Serpentinite and Banded iron formation consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Banded iron formation includes Hematite, Magnetite, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Banded iron formation, the texture, color and appearance plays an important role in determining the type of rock. Serpentinite is available in black, brown, green, grey, white colors whereas, Banded iron formation is available in red, reddish brown colors. Appearance of Serpentinite is Rough and Dull and that of Banded iron formation is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Serpentinite vs Banded iron formation. The hardness of Serpentinite is 3-5 and that of Banded iron formation is 5.5-6. The types of Serpentinite are Jadeitite 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 Serpentinite and Banded iron formation is white, greenish white or grey. The specific heat capacity of Serpentinite is 0.95 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.Serpentinite is heat resistant whereas Banded iron formation is heat resistant, impact resistant, pressure resistant, wear resistant.
