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.   
Phonolite are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

Banded iron formation vs Phonolite 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 Phonolite Reserves. Banded iron formation are distinctive units of sedimentary rock that are almost always of Precambrian age. Phonolite is an uncommon extrusive igneous rock volcanic rock of intermediate chemical composition between felsic and mafic. 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 Phonolite information and Banded iron formation vs Phonolite characteristics in the upcoming sections.

Banded iron formation vs Phonolite 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. Banded iron formation vs Phonolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Banded iron formation and Properties of Phonolite. Learn more about Banded iron formation vs Phonolite in the next section. The interior uses of Banded iron formation include Decorative aggregates and Homes whereas the interior uses of Phonolite include Countertops, Decorative aggregates, Flooring and Homes. Due to some exceptional properties of Banded iron formation and Phonolite, they have various applications in construction industry. The uses of Banded iron formation in construction industry include As dimension stone, Used for flooring, stair treads, borders and window sills. and that of Phonolite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics.

More about Banded iron formation and Phonolite

Here you can know more about Banded iron formation and Phonolite. 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 Phonolite consists of mineral content and compound content. The mineral content of Banded iron formation includes Hematite, Magnetite, Quartz and mineral content of Phonolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite. You can also check out the list of all Sedimentary Rocks. When we have to compare Banded iron formation vs Phonolite, 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, Phonolite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Banded iron formation is Layered, Banded, Veined and Shiny and that of Phonolite is Banded and Foilated. Properties of rock is another aspect for Banded iron formation vs Phonolite. Hardness of Banded iron formation and Phonolite is 5.5-6. The types of Banded iron formation are Algoma-type , Lake Superior-type, Superior-type and Taconite whereas types of Phonolite are Kenyte.
