Fig. 8From: Hadean/Eoarchean tectonics and mantle mixing induced by impacts: a three-dimensional studySurface mobility versus time for 2-D and 3-D cases with and without impacts for three different yield stress values. In 2-D, the plots show the cases with a percentage of surface mobility > 1 equal to 93.28%, 57.14% and 48.29%, from the left to the right panelBack to article page
