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.

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.
