Supplementary electronic material for Chapter 2 Gradmann, S., C. Beaumont, and M. Albertz (2009), Factors controlling the evolution of the Perdido Fold Belt, northwestern Gulf of Mexico, determined from numerical models, Tectonics, 28, TC2002, doi:10.1029/2008TC002326. Introduction The auxiliary material contains three movie files showing the evolution of selected numerical models used in the study of the Perdido Fold Belt, northwestern Gulf of Mexico. 1. Animation_modelR0.mp4: Animation of reference model R0, showing the general evolution of a gravity-driven salt-cored deep-water fold belt on a continental margin. 2. Animation_modelRM1.mp4: Animation of regional model RM1, showing the evolution of a propagating fold belt and allochtonous salt structures above the distal salt basin. 3. Animation_modelRM2.mp4: Animation of regional model RM2, showing the evolution of a propagating fold belt and allochtonous salt structures above the central salt basin.
