Formation

Formation
Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma.   
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.

Aplite vs Banded iron formation 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 Aplite and Banded iron formation Reserves. Aplite is a fine-grained granite composed mainly of feldspar and quartz. Banded iron formation are distinctive units of sedimentary rock that are almost always of Precambrian age. 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 Aplite vs Banded iron formation information and Aplite vs Banded iron formation characteristics in the upcoming sections.
