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.this deposition of material the stream beds were filled and the water forced to a new channel. By continued shifting of streams, irregular layers were deposited with much less uniform bedding than those of marine deposition. It is thought that the material composing the High Plains was laid down in this way upon the red beds, the basal

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.

Red beds with Type-B and Type-C magnetizations are not considered to be generally suitable for palaeomagnetic study.Yes, you are correct, red beds are red because of oxidized iron. Furthermore, you are correct that iron needs to be in the presence of oxygen(in some form) to oxidize. However, the existence of ferric oxides is an observation by which we denote a red bed as a red bed, not an explanation of the red bed's development.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.
