Red beds, also commonly known as continental red beds (CRBs), are globally widespread sedimentary successions depicting an overall reddish-color …Deposition of carbonate sand (often oolitic) in a shallow marine environment and some red clay and anhydrite in a shallowing sea; preceded by the accumulation of a thick sequence of salt beds (halite), some anhydrite, and red clay and silt in shallow highly saline waters. Present only in the subsurface in southern Arkansas. 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.
