Introduction .—Red-colored sediments have always attracted the attention of geologists. A venerable opinion of long standing connects red beds with aridity, thus investing them with an important paleoclimatic significance. Red beds are rather extensive, forming, for instance, close to 15 per cent of the Paleozoic section in the Appalachian ...Stratigraphic cross section along the Red Wall valley.

Jan 1, 2013 · 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.
