Definition
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time
Banded iron formation are distinctive units of sedimentary rock that are almost always of Precambrian age

Formation
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.
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.

All about Marble and Banded iron formation Properties
Know all about Marble and Banded iron formation properties here. All properties of rocks are important as they define the type of rock and its application. Marble belongs to Metamorphic Rocks while Banded iron formation belongs to Sedimentary Rocks.Texture of Marble is Granular whereas that of Banded iron formation is Banded, Trellis. Marble appears Veined and Shiny and Banded iron formation appears Layered, Banded, Veined and Shiny. The luster of Marble is dull to pearly to subvitreous while that of Banded iron formation is earthy. Marble is available in black, blue, brown, grey, pink, white colors whereas Banded iron formation is available in red, reddish brown colors.
