Red beds geology.
Yes, you are correct, red beds are red because of oxidized iron. Furthermore, you are correct that iron needs to be in the presence of oxygen(in some form) to oxidize. However, the existence of ferric oxides is an observation by which we denote a red bed as a red bed, not an explanation of the red bed's development.
