GEOL5700: Fold and Thrust Belts and Orogenic Wedges
One of the earlier mysteries in geology was the discovery in the 19th century of large scale overthrusts in the Alps. Sheets of rock were found to have pushed over large regions with the boundary fa

So, regional differences must be in the horizontal stresses. Reverse faults require crustal compression.
