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.   
Rhyolite is a felsic extrusive rock and due to its high silica content, rhyolite lava is very viscous and is volcanic equivalent of granite.

Banded iron formation vs Rhyolite 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 Rhyolite Reserves. Banded iron formation are distinctive units of sedimentary rock that are almost always of Precambrian age. Rhyolite is a fine-grained igneous rock which is rich in silica. 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 Rhyolite information and Banded iron formation vs Rhyolite characteristics in the upcoming sections.

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 Rhyolite include Arrowheads, As dimension stone, Building houses or walls, Construction aggregate, Cutting tool, For road aggregate, Knives.

More about Banded iron formation and Rhyolite

Here you can know more about Banded iron formation and Rhyolite. 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 Rhyolite consists of mineral content and compound content. The mineral content of Banded iron formation includes Hematite, Magnetite, Quartz and mineral content of Rhyolite includes Biotite, Feldspar, Hornblade, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Banded iron formation vs Rhyolite, 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, Rhyolite is available in grey, white, light black colors. Appearance of Banded iron formation is Layered, Banded, Veined and Shiny and that of Rhyolite is Banded. Properties of rock is another aspect for Banded iron formation vs Rhyolite. The hardness of Banded iron formation is 5.5-6 and that of Rhyolite is 6-7. The types of Banded iron formation are Algoma-type , Lake Superior-type, Superior-type and Taconite whereas types of Rhyolite are Pumice Rocks, Obsidian Rocks, Perlite Rocks, Porphyritic Rocks.. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Banded iron formation is white while that of Rhyolite is colorless. The specific heat capacity of Banded iron formation is 3.20 kJ/Kg K and that of Rhyolite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Banded iron formation is heat resistant, impact resistant, pressure resistant, wear resistant whereas Rhyolite is heat resistant, wear resistant.
