principal ﬂow patterns in the salt canopy that can be inferred from base of salt maps. Continuing deposition superposes local ﬂows due to sinking mini-basins onto the basic ﬂow pattern, but this study demon-strates that the principal ﬂow directions are recorded in the base of salt by the ﬂats and ramps.

Salt tectonics is concerned with the structural geometries and deformation processes associated with the presence of significant thicknesses of rock salt within a sequence of rocks. This is due both to the low density of salt, which does not increase with burial, and its low strength.
This course is a field, lecture and practical based investigation of the extensional tectonics and normal fault patterns of the northern Paradox Basin, SE Utah. Participants examine the superbly exposed, salt-detached, extensional structures of the northern Paradox Basin and the Moab Fault system.

The NW African margin of the Central Atlantic has two major salt basins, the Moroccan (a small part of it located in the Canary Islands of Spain) and the Mauritanian ().Other Upper Triassic to Lower Jurassic salt basins do exist further to the south along the African margin in Senegal, the Gambia and Guinea Bissau (e.g., Tari et al., 2003, Davison, 2005), but these basin segments will not be ...
salt structures whose southern border, against the abyssal plain, displays a spectacular lobate pattern. For almost 20 years, this major structural difference in salt tectonic patterns between the GoM north margin and South Atlantic margins has drawn attention. In terms of processes, whereas salt tectonics in Atlantic-type margins primarily corre-

Apr 12, 2017· Salt tectonics, as a sub-discipline of structural geology, describe deformation structures developing due to the special deformation behaviour of salt (as synonym for a sequence of evaporitic rocks). Salt behaves like a viscous fluid over geological time scales and, therefore, it may flow due to lateral differences in thickness and density of ...

Abstract. In the Gabonese southern Onshore Basin, several oil fields occur below an Aptian salt sequence. Because of the presence of diapirs and salt walls related to post aptian salt tectonics, the quality of the 2D or 3D seismic imaging of the presalt formations stays very insufficient to well define the structural patterns within the traps below the salt.

Salt flowed laterally from the diapirs to form a complex, multi‐level canopy, now partly welded, containing an encapsulated minibasin and capped by suprasalt basins. Salt and minibasin geometries were modified during the Late Cambrian–Ordovician Delamerian Orogeny (ca. 500 Ma). Small‐scale structures such as subsalt shear zones, fractured ...
The shape, size, and type of salt deformation must be mapped and understood in order to map and under-stand the pre-salt tectonics; the pre-salt tectonics must be understood to predict its effects on later depositional and structural patterns. For example, salt domes, pillows, and ridges may form along the edges or more often in
In offshore Angola, the similarity between the pre and post-salt structural patterns suggests that the infrastructure, that is to say, the sub-salt strata, is often implicated in the deformation. In other words, in certain cases, raft tectonics seems to be related and not totally independent of the basement tectonics (basement involvement) .
Salt tectonics receives little attention in most structural geology texts, possibly owing to the paucity of high-quality, accessible salt exposures. However, salt tectonics is of major interest to many practicing geologists, as indicated by the burgeoning of salt-tectonic articles in the professional literature.
Salt tectonics, which lead both directly and indirectly to the formation of paleobathymetric highs, peripheral sinks and persistent structural highs, strongly influenced carbonate and siliciclastic depositional patterns of the Aptian Rodessa Formation.
What is the influence of salt tectonics on the evolution of sedimentary basins and how can we reconstruct such salt features? Michael Warsitzka, PhD student at the Friedrich Schiller University of Jena, explains which complementary methods he uses to better understand salt structures and their relation to sedimentary basins.
