“…The result being that the thickness of salt beneath each of the minibasins decreased during regional shortening, with the resulting increased friction or viscous drag lowering the translation velocity of the salt, and hence also reducing the translation velocity of the minibasins ( cf . Figure 6a,b; sensu Wagner III & Jackson, 2011; Fernandez, Duffy, Jackson, Dooley, Hudec, et al., 2020).…”

Shortening styles in salt-influenced basins can vary markedly, with the volume and distribution of salt prior to shortening being a key control. Here, we use a suite of physical models to examine styles of thin-skinned regional shortening in settings where the preshortening structure comprised minibasins surrounded by salt ('isolated- Highlights• In settings with isolated minibasins and a high salt volume, shortening induces salt flow.• The flow of salt contributes to the translation, tilt and rotation of minibasins during shortening.• A variety of factors control the amount and timing of minibasin translation, tilt and rotation during shortening.• The controls include, among others: boundary conditions, salt pressures, basesalt relief and whether primary and secondary welds have formed.• Fold-and-thrust belts in salt basins can vary in style, being strongly influenced by the volume and distribution of precursor salt.
