reCeNt adVaNCeS iN GeoSCieNCe Salt: deformation, trapping

whereas synkinematic sedimentation induces loading instabilities. At basin scale, thin-skinned deformation may induce extreme upslope salt thinning, leading to the formation of salt welds, as well as massive downs-lope salt thickening. Extensional domains, such as the Angolan margin, can often be divided into three sub-domains. Moving Get price

The influence of shortening and sedimentation on

Abstract This study employs a novel Discrete-Element Modelling approach to investigate the interplay of sedimentation with rejuvenation of diapirs by shortening. The inherent complexity of salt tectonics, the complications encountered when imaging structures beneath salt, and the lack of outcrop analogues, coupled with its importance to petroleum systems, make salt tectonics one of the most Get price

Impacts of Neotectonics and Salt Diaper on the Nile Fan

The Nile Delta composed of two pro-grading sedimentation systems separated by the major Messinian unconformity [3]. During the late Miocene the strait of Gibraltar was closed and the subsequent evaporation of the Mediterranean Sea water led to the deposition of thick salt layers (near the basin center) and forming many incised valleys on the Get price

Hindered Settling: Salt and sediment: A brief history of ideas

Jul 16, 2011Salt can also act as a lubricating layer at the base of a thick sequence of sedimentary rocks. But I am rushing ahead a little bit; salt tectonics is such a new - but rapidly growing - science that salt canopies, despite their widespread presence in the subsurface Gulf of Mexico, were not recognized and described until the 1980s.

Dynamic modelling of passive margin salt tectonics

Aug 31, 2005At a later stage, an allochthonous salt nappe overthrusts the autochthonous limit of the salt. The nature and distribution of major structures depends on the sediment properties and the sedimentation pattern. Strain weakening of sediment favours landward listric growth faults with formation of asymmetric extensional depocentres. Get price

Salt Tectonics and Sedimentation in the Offshore Majunga

Thus, the shale and salt tectonics coexist in the Majunga Basin with the Early Jurassic salt being responsible for the largest share of the deformation. At present, prior to the availability of 3D seismic data, the Majunga salt basin provides an example of the interaction of salt and sediments only on a regional to sub-regional scale. Get price

Numerical modelling of rise and fall of a dense layer in

Diapirs of low-viscosity salt (10 16 Pa s) survive even for high sedimentation rate (e.g. 15 mm a −1) whereas increasing the salt viscosity requires a decrease of the sedimentation rate for the diapir to rise without being buried .
