Timepoint 2

At this point the wedge has started to grow and thrust faults are visible on the surface.

Figure 1. Pure Shear. At frontal forewedge, pure shear shows contraction at the toe of the wedge where active thrusting occurs.
Figure 2. Simple Shear. Dextral shear continues along lateral side.
Figure 3. Dilatation. Contraction localized along both frontal and lateral zones at the toe of each wedge. Also, the frontal zone shows almost no strain across the main divide, but strain increases again at the toe of the retrowedge, but at a value less than the forewedge.
Figure 4. Rotation. Clockwise rotation is postive.
