The wide range of δ97/95Mo values occurs in a paleohydrologic setting in which dense, concentrated, evaporitic marine brines in the Dead Sea Rift valley (δ97/95Mo ~1.6‰) penetrated and interacted with sedimentary rocks of the rift flanks, which included Cretaceous bituminous chalks (δ97/95Mo 0.8‰–1.2‰), before intermixing with Fe-bearing groundwater containing molybdenum of igneous and clastic origin. The δ97/95Mo values higher than seawater (1.6‰–2.3‰) are attributed to Rayleigh isotopic fractionation along the path of the brine migration. Molybdenum isotopes thus reveal a powerful potential to trace the sources and processes governing subsurface metalliferous fluid migration.
