| 摘要 | Fluids liberated from subducting slabs are critical in global geochemical cycles. We investigate the behaviour of Mo during slab dehydration using two suites of exhumed fragments of subducted, oceanic lithosphere. Our samples display a positive correlation of delta Mo-98/95(NIST) (3134) with Mo/Ce, from compositions close to typical mantle (-0.2 parts per thousand and 0.03, respectively) to very low values of both delta Mo-98/95(NIST) (3134) ( -1 parts per thousand) and Mo/Ce (0.002). Together with new, experimental data, we show that molybdenum isotopic fractionation is driven by preference of heavier Mo isotopes for a fluid phase over rutile, the dominant mineral host of Mo in eclogites. Moreover, the strongly perturbed delta Mo-98/95(NIST) (3134) and Mo/Ce of our samples requires that they experienced a large flux of oxidised fluid. This is consistent with chan-nelised, reactive fluid flow through the subducted crust, following dehydration of the underlying, serpentinised slab mantle. The high delta Mo-98/95(NIST) (3134) of some arc lavas is the complement to this process. |
