A unique suit of Wuchiapingian marine red beds in central China representing a specific paleogeography and paleoclimate association.The term red beds usually refers to strata of reddish -colored sedimentary rocks such as sandstone, siltstone or shale that were deposited in hot climates under oxidizing conditions. [1] They are usually formed in terrestrial situations: on land, and in rivers and lakes . The red color comes from iron oxide in their mineral structure.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.

Lower Devonian successions of the Prague Basin, Czechia ...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.
