Geophysical and subsurface data show that the Gorleben salt diapir, which is one of the most extensively investigated diapirs in the world, and other salt diapirs of the Zechstein Formation in Germany contain large blocks (∼80 m thick) of high-density anhydrite inclusions.

The Persian Gulf Basin is an elongate, margin sag-interior sag, sedimentary basin spanning the last 650 Ma along the northeastern subducting margin of the Arabian Plate and is the largest basin with active salt tectonism in the world. This basin is asymmetrical in NE-SW cross section with sediments thickening from 4,500 m near the Arabian ...
Salt tectonics and structural inheritance provide an alternative approach to solving many long-standing structural problems in the Silica Nappe. First, mapping results suggest initial salt movements as early as the Early Triassic, and continuous diapir growth and minibasin formation. We propose that the pre-orogenic diapirism may have been ...
2. Mechanics of salt flow2.1.. OverviewFor most of the past 70 years, the prevailing view of salt tectonics was that its mechanics were dominated by salt buoyancy (see Jackson, 1995, Jackson, 1997a, Jackson, 1997b for historical reviews). Sediments were envisioned as a dense fluid having negligible yield strength.
Here, we discuss the role salt tectonics can play in a number of key energy transition technologies, namely, energy storage as gas in salt caverns (e.g. hydrogen and compressed air), CO2 storage ...
2.3. Initial sedimentary cover above salt. In all salt margins where the seaward salt pinch-out is clearly imaged, the most distal part of the salt basin appears to be covered by sediments soon after the end of evaporitic sedimentation, as exemplified in most Atlantic passive margins (e.g. West Africa: Marton et al., 2000, Tari et al., 2001; Brazil: …

We focus here on the deformation of competent intrasalt beds in different endmember modes of salt tectonics, even though combinations are common in nature, using a combination of conceptual, numerical, and analog models, and seismic data. ... with the resulting stringers rotated to near-vertical orientation and entrained in ductile salt that is ...
Salt tectonics is the study of how and why salt structures evolve and the three-dimensional forms that result. A fascinating branch of geology in itself, salt tectonics is also vitally important to the petroleum industry. Covering the entire scale from the microscopic to the continental, this textbook is an unrivalled consolidation of all ...

Salt tectonics in the North Sea cannot be characterized simply. The salt experienced a multievent history with diapirism, multiple episodes of rifting, and local and regional basin inversion. Because the degree to which any particular tectonic event impacted a specific salt structure differs, there is a wide variety in geohistory and …
A synthesis of deformation patterns within and around the Thaumasia Plateau, Mars, points to a new interpretation for regional deformation and the origin of Valles Marineris and associated outflow channels. The morphology of the Thaumasia Plateau is typical of thin-skinned deformation, akin to a "mega-slide," in which extensional deformation in Syria …
Historically, salt has played an important role in petroleum exploration since the Spindletop Dome discovery in Beaumont, Texas in 1906. Today, much of the prime interest in salt …
We identify four structural provinces that contain distinct groups of structural elements believed to be genetically related: (1) far-eastern Gulf, in which no major Cenozoic deformation is seen; (2) eastern Gulf, defined mainly by a middle-late Miocene linked system of extension and contraction; (3) central Gulf, in which Oligocene updip ...
South Atlantic divergent margin evolution: rift-border uplift and salt tectonics in the basins of SE Brazil. Authors: W. Mohriak [email protected], M. Nemčok, and G. Enciso Authors Info & Affiliations. ... Continental uplift may be invoked as the main cause of salt mobilization, generating prograding clastic wedges that thickened basin-wards ...
Most deepwater salt basins are found on passive margins, although a few of these passive margins are now in convergent settings (Fig. 1).The reason for the dominance of passive margins in deepwater salt tectonics is that the early stages of continental rifting offer many opportunities for isolated conditions that can lead to salt …
Physical model studies of salt tectonics related to thick-skinned extension have been largely confined to 2Dstructures. ... Diapir crests and entrained salt bodies are nucleation sites for the ...
As usual in salt tectonics analogue modelling the high-viscosity silicone polydimethylsiloxane (PDMS) polymer from Clearco Products Co (PSF-20,000,000 cSt) was used as a proxy for rock salt (referred to in the text as "salt" for simplicity). ... formerly interstratified within a layered evaporite sequence (LES) that are entrained and ...

(b) Kinematic model based on recent physical models showing effects of salt …
These salt-bearing margins are typically characterized by pronounced post-rift salt tectonics with variable and complex structural styles and evolution. We use a lithosphere-scale geodynamic numerical model to investigate the role of varying post-rift sediment fluxes and progradation rates on rifted margin salt tectonics.

In this paper we examine the role salt tectonics can play in a number of key energy transition technologies, namely, energy storage as gas in salt caverns (e.g. hydrogen and compressed air), CO2 storage, and geothermal energy. For each of these technologies we explore: i) fundamental concepts and driving forces; ii) how and why the …

Historically, salt has played an important role in petroleum exploration since the Spindletop Dome discovery in Beaumont, Texas in 1906. Today, much of the prime interest in salt tectonics still derives from the petroleum industry because many of the world's largest hydrocarbon provinces reside in salt-related sedimentary basins (e.g. Gulf of Mexico, …

Salt tectonics can occur at various stages, but early salt activity can create a structural inheritance which compartmentalizes the building of the sedimentary succession and the mechanical architecture of the orogenic wedge. Sub-Alpine fold-and-thrust belts commonly show evidence of inherited salt-related structures, which were mostly ...
