Fig. 9From: Hadean/Eoarchean tectonics and mantle mixing induced by impacts: a three-dimensional studySurface mobility and impactor size versus time for cases with yield stress 125 MPa in 2-D and 3-D. Only the larger impacts are shown as labelled on the right-hand vertical axis. In 2-D only impacts generating a thermal anomaly that intersects the simulation plane are plotted. In 2-D, the case with impacts is the same as that in the right panel of Fig. 8Back to article page
