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.
1. Introduction. Marine red beds are common in Phanerozoic strata, and can be classified broadly into three groups: oceanic red beds, shelf or epicontinental marine deep-water red beds, and nearshore shallow-water red beds (Brett et al., 2012, Rong et al., 2012, Hu, 2013, Song et al., 2017 and their references).Silurian red beds are widely …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.The red beds consist essentially of siliciclastic detrital materials including sandstone, silt, and clay, with some thin layers of micritic limestones and edaphic carbonates. This sequence was formed in a sedimentary framework typical of a low sinuosity fluvial system of braided type. The copper mineralization is hosted by a fine-grained ... ….

Abstract. The Cretaceous oceanic red bed (CORB) is a newly opened window on global oceanic and climate changes during the Cretaceous greenhouse world. As a result of the International Geoscience Programmes 463, 494 and 555 (2002–2010), CORBs have been documented in many places by numerous publications.Some workers have suggested that there is a link between recent CO 2-rich fluids and this red-bed bleaching (Allis et al. 2001; Wigley et al. 2013; Kampman et al. 2014; Ogata et al. 2014). Of key interest at the study site is the fate of the iron; its reduction and mobilization is implied by the bleaching patterns.thick sequence of red beds was formed.
