In the Schleswig-Holstein area, salty groundwaters are not always spatially related to the presence of shallow salt structures. Furthermore, hydrogeochemical data point to instable salinity profiles and to the occurrences of deep brines close to the surface. Therefore, complex interaction between shallow and deep solute migration must occur.Numerical simulation of fluid flow, mass and heat transport have been carried out in order to understand the role of shallow salt dissolution and young geological features on groundwater flow as well as to investigate the interrelationships between shallow and deep aquifer-systems. For these purposes, a shallow (-500 m) and a deep profile model (-5 km) have been constructed.The results indicate that different flow regimes coexist within the study area. Shallow brine migration is strongly controlled by the geological features of the basin such as faults, Pleistocene channels and sand layers. Furthermore, shallow salt dissolution is the major cause for gravitational convection in the deeper aquifers. This source of salinization from above leads to the formation of instable salinity profiles at 2 km depth. Further interactions between shallow and deep fluid flow exist in the eastern part of the basin where brine upconing is due to both topographydriven flow and thermohaline convection. The simulations also showed that the hydraulic conductivity of the stratigraphic units influences the brine regime on a regional scale. Gravitational convection is likely to occur in permeable units located near shallow salt structures, while thermohaline convection persists within thick permeable units in which salt dissolution is not the dominant process.The presented study provides new insights into fluid flow processes at basin scale. The described flows could develop in any geothermal basin hosting salt diapirs which pierce shallow aquifer systems.

“…The Glueckstadt Graben was not essentially inverted during the Late Cretaceous-Early Tertiary when reverse faults and flexures developed along the EFS in the south. In the Glueckstadt Graben, the Late Cretaceous-Early Tertiary compression caused increased salt activity (Kockel 2002;Maystrenko et al 2006). In the Cenozoic, a depocentre developed within the central North Sea (Ziegler 1990;Scheck-Wenderoth and Lamarche 2005).…”

“…To resolve these, an attempt has been made to look inside of the Glueckstadt Graben by use of 3D gravity backstripping, based on a 3D structural model of the deepest Triassic structure of the Central European Basin System, the Glueckstadt Graben (see Fig. 3; Maystrenko et al 2006). In addition, a detailed density model was performed along two cross-sections across the central part of the Glueckstadt Graben and was supplemented by 2D magnetic modelling.…”

The structure of the Glueckstadt Graben has been investigated by use of 3D gravity backstripping technique and by 2D gravity and magnetic modelling. Subtracting the gravity effects of the Meso-Cenozoic sediments together with Permian salt reveals a positive residual anomaly within the Glueckstadt Graben. This anomaly includes two local maxima over the Westholstein and Eastholstein Troughs. The 2D gravity models point to the presence of a high-density body within the lower crust of the Glueckstadt Graben. In addition, the results of 2D magnetic modelling indicate that the central part of the high-density body is overlain by an area with high susceptibility. Most probable, the formation of this high-density body is a result of complex poly-phase tectonic history of the study area. Finally, the results of gravity modelling indicate that Permian salt is not homogeneous. 3D gravity analysis and, especially, 2D gravity modelling have distinguished the differences in degree of salt saturation in salt-rich bodies, and elucidate the proportion of Rotliegend salt.

Thanks to a continuous effort for unravelling geological records since the early days of coal and petroleum exploration and water management, the architecture and chrono-litho-stratigraphy of most sedimentary basins has been accurately described by means of conventional geological and geophysical studies, using both surface (outcrops) and subsurface (exploration wells and industry seismic reflection profiles) data. However, the understanding of the early development and long term evolution of sedimentary basins usually requires the integration of even more data on the deep Earth, as well as quantifications by means of kinematic-sedimentological and thermomechanical modelling approaches coupling both surface and deep processes.In the last twenty years, huge national and international efforts, frequently linking academy and industry, have been devoted to the recording of deep seismic profiles in many intracratonic sedimentary basins and offshore passive margins, thus providing a direct control on the structural configuration of the basement and the architecture of the crust. Seemingly, needs for documenting also the current thickness of the mantle lithosphere and the fate of subducted lithospheric slabs have led to the development of more academic and new tomographic techniques. When put together, these various techniques now provide a direct access to the bulk 3D architecture of sedimentary basins, crystalline basement and Moho, as well as underlying mantle lithosphere. Inherited structures, anisotropies in the composition of the sediments, crust and underlying mantle as well as thermicity and phase transitions are now taken into account when predicting the localization of deformation in the lithosphere during compression and extension episodes, and reconstructing the geodynamic evolution of rift basins, passive margins or even foreland fold-and-thrust belts.Source to sink studies also provide accurate estimates of sedimentary budget at basin-scale. Extensive use of low temperature chrono-thermometers and coupled kinematic, sedimentological and thermal models allow a precise control on the amount and timing of erosion and unroofing of source areas, but also the reconstruction of the sedimentary burial, strata architecture and litho-facies distribution in the sink areas.Coupling deep mantle processes with erosion and climate constitutes a new challenge for understanding the present topography, morphology and long term evolution of continents, especially in such sensitive areas as the near shore coastal plains, low lands and intramountain valleys which may be subject to devastating flooding and landslides.In addition to the search for hydrocarbon resources, other societal needs such as CO 2 storage and underground water management will benefit from upgraded basin modelling techniques. New 2D and 3D basin modelling tools are progressively developed, coupling in different ways deep thermo-mechanic processes of the mantle (asthenosphere and lithosphere), geomechanics of the upper crust and sediments (compactio...
