Formation
Jaspillite is a type of sedimentary rock which is formed by the compaction and sedimentation of pieces of broken or weathered rocks and minerals.
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 Jaspillite and Banded iron formation
Here you can know more about Jaspillite 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 Jaspillite and Banded iron formation consists of mineral content and compound content. The mineral content of Jaspillite includes Coesite, Quartz, Sand and mineral content of Banded iron formation includes Hematite, Magnetite, Quartz. You can also check out the list of all . When we have to compare Jaspillite vs Banded iron formation, the texture, color and appearance plays an important role in determining the type of rock. Jaspillite is available in red, reddish brown colors whereas, Banded iron formation is available in red, reddish brown colors. Appearance of Jaspillite is Banded and Glassy and that of Banded iron formation is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Jaspillite vs Banded iron formation. The hardness of Jaspillite is 3 and that of Banded iron formation is 5.5-6. The types of Jaspillite are Algoma-type , Lake Superior-type and Superior-type 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 Jaspillite and Banded iron formation is white. The specific heat capacity of Jaspillite is 3.20 kJ/Kg K and that of Banded iron formation is 3.20 kJ/Kg K.
