Join us today as we discuss one of the more important ancient rock formations - Banded Iron Formations or otherwise known as BIF's in the geologic community.  Wherever found, they provide us with Iron ore - some of the best on the planet.  In this episode, we delve into the geologic story of how these important and beautiful rocks formed.  There is some newer research that has altered some earlier thinking on BIF formation.  We hope you enjoy.
