Here, we use Ba (barium) stable isotope measurements to investigate the origin of DMM heterogeneity. Barium is a highly incompatible element that is enriched up to 100 times more in E-MORB compared to normal MORB (N-MORB) (3, 17).Barium is also fluid mobile and is one of the most commonly used elements to track slab-derived fluids in subduction zones ().
