“…Recently, a few models have been implemented in full 3D (e.g. Guglielmo et al, 1999;Scheck et al 2003a, b;Ismail-Zadeh et al;2004). 3D visualization of the results of analogue modelling have helped to elucidate the complex geometry of salt diapirs (Guglielmo et al, 1999), demonstrating changes of sedimentation, deformation, and underlying salt thickness through time.…”

The Glueckstadt Graben is prominent structure of the Central European Basin System, where the sedimentary patterns are extensively affected by Permian salt movements. The relations of the sedimentary patterns to salt structures have been analyzed through present-day distributions of sediments. In addition, a three-dimensional backward modelling approach has been applied to determine the original salt distribution in response to the unloading due to sequential backstripping of the Cretaceous when the area of the Glueckstadt Graben was tectonically silent. Therefore, our study supports the concept of tectonically induced salt movements which can be interrupted during the absence of tectonic forces. Salt movements were reactivated in the marginal troughs by compressional forces 4 during the latest Late Cretaceous-Early Cenozoic. Paleogene-Neogene salt withdrawal led to the growth of N-S oriented salt structures mainly at the margins of the basin. This phase of salt tectonics correlates temporally with almost W-E extension. This indicates a renewed change in tectonic regime after Late Cretaceous-Early Cenozoic compression.

“…Unlike our previous three-dimensional (3-D) visualizations of physical models (Guglielmo et al, 1997(Guglielmo et al, , 1999, we here incorporate allochthonous salt sheets and the effects of regional compression. We suggest how overburden isochores (and isopachs) can record the former shape of salt extrusions before they were shortened.…”

3-D Visualization and Isochore Analysis of Extensional Diapirs Overprinted by Compression

Palinspastic restorations elucidate geologic and hydrocarbon-migration histories in salt provinces; however, salt dissolution and salt flow in and out of the section plane make it difficult to determine the shape of salt bodies before deformation, which hampers accurate restorations. Three-dimensional computer visualization of a physical model and analysis of isochores provide clues to the original shape of allochthonous salt bodies that were emplaced during extension and later compressed.Initially, tabular salt (simulated by viscous silicone) was regionally extended as synkinematic sediments accumulated. Extension triggered the rise of reactive salt walls that subsequently were shortened coaxially. Contraction produced curvilinear faulted folds, pop-ups, detachment anticlines, and pinched-off salt walls. Salt was squeezed to higher levels through fault-bounded vents in the roof. Three generations of stacked salt sheets were extruded and later acted as structural detachments.Isochore plots in the overburden show how patterns of sedimentation, deformation, and underlying salt changed through time. Isochores of prekinematic strata recorded only strain, with thinned belts recording early extension and paired, thickened belts recording late shortening. In con-1095 trast, isochores of synkinematic strata recorded mostly deposition on exposed structures, with thicks recording salt expulsion, block grounding, and roof collapse and thins recording diapir rejuvenation. Synkinematic isochores also recorded the former shape of subsequently shortened allochthonous salt, showing palinspastically how the weaker salt absorbed much more shortening than the stronger sediments encasing it. Isochore analysis thus improves two-dimensional and three-dimensional restorations of salt tectonics.
