Influence of sedimentary density variations in décollement-related fold-and-thrust belts: insights from centrifuge analogue modelling

We present an innovative centrifuge analogue modelling approach to evaluate the influence of density contrast on structure location and vergence affecting thin-skinned compressional settings. Our natural prototype involves a detached foreland basin characterized by a basal ductile evaporitic décolle...
