Red beds geology.

Red beds (or redbeds) are sedimentary rocks, typically consisting of sandstone, siltstone, and shale, that are predominantly red in color due to the presence of ferric oxides. Frequently, these red-colored sedimentary strata locally contain thin beds of conglomerate, marl, limestone, or some combination of these sedimentary rocks.Permian System In Permian Period: Basin sedimentation …increase in eolian (wind-transported) sands, red beds, and evaporites.
