Subduction flux comparison. Panel a. crustal production rates (km2/yr) from ref. 39 plate reconstruction in blue, and subducted area (km2/yr) from the updated model37 in black (b). Green line shows depth against the surface area (millions of km2) of the maximum votes for the combined models (similar to Fig. 7) and scaled for the radius. Compared against depth-converted subduction flux from panel a as based on alternative sinking rates; black and light grey are globally averaged sinking rates of 1.1 and 1.3 cm/yr respectively, and darker grey and red are faster alternatives which assume 5 cm/yr in the upper mantle and 1.1 and 1.3 cm/yr in the lower mantle, respectively.
