Banded Iron Formations and what they tell us about the Earth's evolution

The formation of Banded Iron Formations (BIFs) are so important as a resource of the element iron, but also as they tell us about how our atmosphere evolved some 2,500 million years ago. In this episode, we talk about the major theory of the formation of BIFs as well as some alternative theories, and what BIF's can tell us about how the evolution of simple blue-green algae changed our Earth for ever!Support the show
