It is fair to say that ochres and their origins are poorly discussed in the academic geological literature. Though ubiquitous in the landscape, they are largely ignored by most geologists. They occasionally pique the interest of economic geologists but are generally dismissed and shovelled away in ...Red beds provide further evidence for atmospheric redox change. They derive from wind-blown dust or river-transported grains coated with red-colored hematite (Fe 2 O 3). Before ∼2.3 Ga, red beds are very rare, whereas afterwards red beds are ubiquitous.
