What do Proterozoic-aged red beds and banded iron formations tell us about the Earth's early atmosphere?

Banded iron formations indicate that there were oxygen-rich and oxygen-poor episodes during Earth's early atmosphere. Banded iron formations first appear in the Archean, 3 billion years ago. Unbanded iron deposits (red beds) from the Proterozoic, 1.8 billion years ago, indicate that the atmosphere became oxygen rich and that oxygen-poor episodes were no longer prevalent.

What is the relationship between red beds and oxygen in the atmosphere?

Red beds are sedimentary rocks that derive their color from iron oxide minerals that form in oxidizing conditions. The presence of abundant red beds in the geological record can indicate periods of high oxygen levels in the atmosphere, as iron is more likely to be oxidized in the presence of free oxygen.
