The deformation includes box folding, graben and reactive diapirs, slumping, multiple salt breakouts, salt canopies, rafts, stacked salt flows, diapir subsidence, diapir roof dismemberment, arcuate grabens with listric faults, salt welds, and grounding and colliding rafts. R afts may be free floating, fully grounded, or partially grounded. Please check how you can use our animations before downloading it. This animation shows a series of photographs taken during deformation of a scaled physical model. The animation illustrates a map view of the complex evolution of an allochthonous salt sheet during progradation.
Illumination is from the right.
Sediment progradation is shown as changes in color and texture of sand in the left side of the animation. The animation lasts 12 seconds and represents approximately 54 hours of the original experiment. Percentages of elapsed time listed below show the approximate age and duration of each stage with respect to the entire animated history. The pressurized salt lifts and deforms the prekinematic layer into a seaward-verging box fold, which forms by bending not buckling. The frontal hinge of this fold is sinuous in map view owing to uneven rates of salt flow to the fold's core.
