Inter-mineral Mg isotope fractionation during hydrothermal ultramafic rock alteration: Implications for the global Mg-cycle

Both riverine and ocean waters are enriched in 24Mg compared to the homogeneous chondritic Mg isotopic composition of the Earth's mantle requiring a fractionation step that is generally attributed to low temperature continental crust weathering. Here we present new observations that indicate th...
