    • Although FeHR/FeT ratios exceeding 0.38 are strongly indicative of sediment deposition in an anoxic water column, anoxic deposition can also yield lower ratios if the flux of clastic material is sufficient to overwhelm the water-column flux of iron. This happens, for example, in turbidite intervals in the Black Sea (22, Also, localized situations of preferential continentally derived iron oxide deposition or sediment iron remobilization can yield FeHR/FeT ratios of greater than 0.38, as is sometimes the case in inner shore environments (23, However, we are aware of no instances whereby oxic deposition in fully marine settings has resulted in FeHR/FeT ratios of greater than 0.38, and this is the case for both continental margin sediments and deep-sea sediments such as red clays 23, As further evidence of enhanced iron deposition in pre-Drook sediments, we highlight that many intervals of the Gaskiers diamictite weather blood red in the field, in stark contrast t
