Banded Iron Form


Banded iron formations, also known as taconite, are made of iron oxide layers alternating with iron-rich chert or jasper. The iron oxide is gray and the chert or jasper is generally red. One of the puzzles posed by these rocks is that the layers are only a few centimeters thick even though the formations themselves are massive. Image: Wikipedia Commons
