Definition
Cataclasite is a type of cataclastic rock that is formed by fracturing and comminution during faulting. It is normally cohesive and non-foliated, consisting of angular clasts in a finer-grained matrix
Banded iron formation are distinctive units of sedimentary rock that are almost always of Precambrian age

Archaeological Significance
Formation
Cataclasiste rocks mainly form by pressure deep under the Earth's surface, 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.

Cataclasite vs Banded iron formation Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Cataclasite vs Banded iron formation characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Cataclasite and Properties of Banded iron formation. Learn more about Cataclasite vs Banded iron formation in the next section. The interior uses of Cataclasite include Decorative aggregates and Homes whereas the interior uses of Banded iron formation include Decorative aggregates and Homes. Due to some exceptional properties of Cataclasite and Banded iron formation, they have various applications in construction industry. The uses of Cataclasite in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate and that of Banded iron formation include As dimension stone, Used for flooring, stair treads, borders and window sills..
More about Cataclasite and Banded iron formation
Here you can know more about Cataclasite 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 Cataclasite and Banded iron formation consists of mineral content and compound content. The mineral content of Cataclasite includes Albite, Apatite, Augite, Biotite, Calcite, Enstatite, Epidote, Feldspar, Micas, Muscovite or Illite, Pyroxene, Quartz 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 Cataclasite vs Banded iron formation, the texture, color and appearance plays an important role in determining the type of rock. Cataclasite is available in brown, green, white, yellow colors whereas, Banded iron formation is available in red, reddish brown colors. Appearance of Cataclasite is Dull and Banded and that of Banded iron formation is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Cataclasite vs Banded iron formation. The hardness of Cataclasite is 3-4 and that of Banded iron formation is 5.5-6. The types of Cataclasite are Protocataclasite, Mesocataclasite, Ultracataclasite and Foliated cataclasite 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 Cataclasite is black while that of Banded iron formation is white. The specific heat capacity of Cataclasite is 0.84 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.Cataclasite is heat resistant, impact resistant, pressure resistant whereas Banded iron formation is heat resistant, impact resistant, pressure resistant, wear resistant.
