We infer system scale fluid flow in the Late Jurassic Salt Wash fluvial succession (SW USA) by plotting uranium deposit distribution against sedimentological data, using uranium distribution as a proxy for subsurface fluid flow. More than 90% of Uranium deposits in the Salt Wash occur where sandstone comprises 40-55% and sand-rich channel-belts form 20-50% of the succession, which coincides with changes in channel-belt connectivity and gross-scale architecture. The paucity of uranium below these cut-off values, suggests fluid flow is related directly to predictable downstream fining and facies variations in distributive fluvial systems.
