Subduction zone lengths. a Total global subduction zone length derived here from the plate tectonic reconstructions of the PALEOMAP project and from Deep Time MapsTM, compared to lengths derived from seismic tomography (Van Der Meer et al.21 shown in red) and from kinematic modelling18. Error estimations (grey) based on observations, direct plate imaging, timing of collisions and relative plate motions (see ‘Methods’ and Supplementary Fig. 2). b Global length of continental arcs17 (left axis) and the cumulative proportion of young Zircon grains16 (shown in red, right axis). c Ridge generation rate via revised sea-level inversion method29, original predictions shown as grey dashed line, revised predictions (see text) shown as black line.
