Animations of Salt Diapirs
For example, a salt layer can continuously or episodically evolve into irregular allochthonous salt sheets, salt pillows, diapirs, walls with overhangs, etc. Accurate visualization and interpretation of how these salt-related structures develop through time are complex but are motivated by economic implications: salt structures are highly ...

Figure 3: Experimental set-up for allochthonous salt-sheet simulations. Salt is deposited in left 29 km of a 70 km wide domain bounded by fixed walls. Sediment layers are added in batches (shown by green and yellow layers), and in two separate areas: one on the back of the salt sheet to build the sediment overburden and the other in front of the salt sheet …
Rising and subsiding diapirs | Applied Geodynamics Laboratory
Allochthonous salt sheets can extend for hundreds of square miles down the continental slope. These sheets spread under their own weight and under the weight of overlying sedimentary layers, which glide down slope carried by the underlying mobile salt.
Allochthonous Salt Sheet Growth: Implications for Thermal History …
Allochthonous salt sheets cover large portions of the Burgos and Perdido basins in Mexico. Salt extrusion began in Eocene times with extensive run out, probably triggered by the Laramide orogenic compression. Rapid sedimentation in the Oligocene/Miocene dammed the salt sheets at the seaward edge.

The diapirs and allochthonous salt sheets of the Flinders Ranges were also a key component of the basin framework in which strata containing Ediacaran fauna were deposited. View.
Abstract: Deformation Styles of Allochthonous Salt Sheets …
The growth history of allochthonous salt sheets and the subsequent deformation and formation of overlying roof geometries (e.g., roho and counterregional salt systems, and salt wall and minibasin formation) has been explored in the past using geometric restorations of seismic interpretations, as well as, physical and numerical …
Advance of allochthonous salt sheets in passive margins …
Some allochthonous salt sheets are emplaced at significant depths, such as source-fed thrusts or delamination wings (Hudec and Jackson, 2006; Rowan, 2017). Others, however, represent a form of ...
Allochthonous salt advance recorded by the adjacent syn …
This paleo-relief is filled by syn-kinematic, alluvial-to-colluvial breccias (FA-8), resulting from the erosion of an extruding allochthonous salt sheet. These breccias were sedimented at the front of the advancing salt sheet and then were overrode. The salt sheet finally overlayed all the previous deposits and covered the sub-basin.

AAPG Datapages/Archives: Structural Styles and Evolution of
In "counter-regional" systems, which are more typical of the shelf, salt rises through south-leaning feeder stocks and flows both downdip and along strike to form allochthonous sheets. In "salt stock canopy" systems, which are more typical of the upper slope, bulb-shaped salt stocks expand outward and form salt canopies.
Allochthonous salt sheet growth: Thermal implications for …
The rapid extrusion of thick allochthonous salt sheets, and the associated transient heat flow effects, can also cause peaks in oil generation, in places postdating the trap formation during the Oligo-Miocene folding event. The principal Tithonian source rock is predicted to have remained in the oil window since Paleogene times, despite being ...
Salt Glacier and Composite Sediment-Salt Glacier Models …
Allochthonous salt sheets in the northern Gulf of Mexico were emplaced as extrusive "salt glaciers" at the sediment-water interface. Massive dissolution was suppressed by a thin carapace of pelagic sediments. During emplacement, several hundred meters of bathymetric relief restricted rapid sedimentation to outside the glacial margins. The …

The Discrete Element Method (DEM) was used to model the advance of allochthonous salt sheets through differential loading. The effects of basal slope angle, initial salt thickness, sediment thickness, loading time, progradation rate, and the mechanical strength of the overburden were tested to determine their influence on the …

During this period, allochthonous salt continued to flow basinward in advance of the prograding depocenter until the salt became encased by sediments sometime during the Pleistocene (Figure 4A see animation). Contractional features developed where the advancing salt sheet amalgamated with the salt stock.
