Fig. 8: Mass-balance calculation results of subduction sulfur input and output.
From: Uncovering and quantifying the subduction zone sulfur cycle from the slab perspective

a Subduction sulfur input and output (30–230 km) categorized by source. b Comparison of subduction sulfur input vs. output. Sulfur influx and outflux estimations are given in the inset table. Labeling of estimates refers to source data (see inset), E to Evans2; H to Hilton et al.50; K to Kagoshima et al.78; L to this study; W to Wallace51; and M to Canfield19, Alt and Shanks22, and Alt et al.21. Uncertainties of estimates indicated with dashed rectangles. No errors are shown if they were not provided in the original study. Note that there is no output data for M.
