Red beds geology.
These well known red beds occur on all continents and they were formed in various geological periods . The oldest are Proterozoic ( 1.5 billion years) and the most recent ones are of Miocene age (6 million years). They are red by fine disseminated hematite iron oxide impregnating their clay minerals. They can be fine grained clay stones ...

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. Pre-2.3 Ga red beds result from ground water contamination by the post-2.3 Ga atmosphere. Krynine (1950) suggested that red beds were formed primarily by the erosion and redeposition of red soils or older red beds. A fundamental problem with this hypothesis is the relative scarcity of recent red colored alluvium, and Van Houten (1961) developed the idea to include the in situ (early diagenetic) reddening of the sediment by the dehydration of brown or drab colored ferric hydroxides.
