Another look at compression a sandpack that has been deformed by extension. In this elastic base model, early normal faults rotate to lower dip, and some experience localized reactivation during shortening. To get more fault reactivation/inversion, materials of strong mechanical contrast and appropriate orientation to stress field would be needed. I also think sidewall drag is a problem here, so stay tuned for an open sided model that I will cut into slices.
