Abstract
The south front of the Alps in northern Italy contains a Neogene S-vergent fold-thrust belt. It affects the crust of the Adria plate, a series of shelf sediments, and S Alpine foredeep fill. The belt shows that after collision, the Alps assumed the bivergent wedge shape of an intracratonic compressional belt, notwithstanding its long prior history of N-vergent subduction and thrust imbrication.
