Post-impact porosity distribution for two specific cases of shape-changing collisions, as indicated in the plot. The porosity calculation takes into account compaction as well as the increase of macroporosity. For comparison, the porosity distributions resulting from compaction only are shown as well. The final average porosity (compaction plus addition of macroporosity by reaccumulation) is 78.8% (Rp = 100 m) and 79.2% (Rp = 300 m), respectively, while the initial porosity was 77.8%.
