Timepoint 1

At this timepoint the main body of the terrane is colliding into the sand indentor for the first time.

Figure 1. Pure Shear
Figure 2. Simple Shear. Dextral shear concentrated along lateral accretion zone.
Figure 3. Dilatation
Figure 4. Rotation. Clockwise rotation is positive
Note: Each figure displays erroneous strain patterns in the lower left. At this timepoint and location there should not be any strain, and the error is probably due to a particle tracking mistake.
