Fig. 6: Sulfur concentrations in fluids and slab water fluxes used for subduction sulfur output estimate.
From: Uncovering and quantifying the subduction zone sulfur cycle from the slab perspective
a [S]fluid derived from different lithologies in the subduction zone calculated by DEW model. Numbers in brackets refer to oxygen fugacity (relative to FMQ buffer) used at certain P–T conditions. Shaded areas indicate [S]fluid variations if fO2 changes within ±1 unit. Sulfur species and proportions at every point are given in Supplementary Fig. 2. b Depth‐dependent water flux released from global subducting slabs49. Water flux is calculated every 10 km between 50–100 km. For example, about 0.91 × 1014 g yr−1 H2O is dehydrated from the upper volcanic layer over the depth interval 80–90 km (corresponding to X-axis 90 km). Source data are provided in Supplementary Data.
