This diagram presents grain boundary outlines of the high strain zones shown on the previous page. Two types of high strain zones can be distinguished: (1) relative long high strain zones at angles of 20-50° with respect to the SZB and (2) shorter high strain zones with inclinations of 50-80° with respect to the SZB. Note that this general strain distribution pattern is preserved over the entire experiment.

The aforementioned changes in positions of intermediate to high strain zones can be observed by the traces of the highest still interconnected contour interval.
