Individual components for synthesized grain size distributions. The thin solid, dashed, and dot-dashed lines represent individual components processed by disruption (shattering) for 3 Myr in Panels (a) and (b), and for 10 Myr in Panels (c) and (d), growth for 10 Myr in Panels (a) and (b) and for 30 Myr in Panels (c) and (d), and shock, respectively. The thick solid line shows ng,s(a) = ngrow(a, tgrow) + 0.8nshock(a). The dotted line shows the MRN size distribution adopted in this paper. Panels (a) and (c) present silicate while Panels (b) and (d) show graphite.
