Banded iron formation vs Eclogite


Definition

Definition
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature   
Banded iron formation are distinctive units of sedimentary rock that are almost always of Precambrian age

Formation

Formation
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.   
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 Eclogite and Banded iron formation

Here you can know more about Eclogite 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 Eclogite and Banded iron formation consists of mineral content and compound content. The mineral content of Eclogite includes Amphibole, Coesite, Corundum, Dolomite, Garnet, Kyanite, Lawsonite, Paragonite, Phengite, Pyroxene, Quartz, Rutile, Zoisite 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 Eclogite vs Banded iron formation, the texture, color and appearance plays an important role in determining the type of rock. Eclogite is available in black, brown, colourless, green, grey, pink, white colors whereas, Banded iron formation is available in red, reddish brown colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Banded iron formation is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Eclogite vs Banded iron formation. The hardness of Eclogite is 3.5-4 and that of Banded iron formation is 5.5-6. The types of Eclogite are Not Available whereas types of Banded iron formation are Algoma-type , Lake Superior-type, Superior-type and Taconite.
