... in this paper. To determine the timing of the onset of diapirism. To describe the detailed geometry of the upturned overburden on salt diapir flanks; and shed new light on the processes that produced stratal upturn and thinning against the Lusitanian diapirs. To describe the occurrence of two...

... channel, a significant part of the overburden load is transferred to the solid fraction of the subducting material, and the mechanical behavior gradually changes to that of a consolidated media with a continuous solid matrix (cf. Nankai and Barbados; Saffer, 2003 ; Calahorrano et al., 2008...

...Mehrdad Darijani; Colin G. Farquharson; Peter G. Lelièvre ABSTRACT Gravity signatures from features associated with the footprints of uranium deposits within the sandstones and basement of the Athabasca Basin are masked in the measured gravity by the contribution from glacial sediments (overburden...

... reservoirs beneath the Base Permian Unconformity. Its drape (supra-crop) by Upper Permian (Zechstein Super Group) evaporites creates the seal. The complexity of its overburden means that an accurate picture of the Breagh structure only emerges after accurate depth-conversion that takes the effects...

... that, by including converted S-waves; one may obtain more robust estimates of salt exit points that do not depend on the salt and overburden velocities. When exiting the salt, a significant amount of the P-waves are converted to S-waves. Compressional and shear phases emerging from a common origin have been used...

... within the salt drives salt flow (“salt squeeze-out”). (2) Basinward tilting of a salt-overburden sequence that is uniform in thickness. In this scenario, elevation-head gradient within the tilted salt layer initiates flow. In both scenarios, overriding rocks, which are mechanically coupled...

...Jennifer Ziesch; David C. Tanner; Charlotte M. Krawczyk ABSTRACT For both modeling and management of a reservoir, pathways to and through the seal into the overburden are of vital importance. Therefore, we suggest applying the presented structural modeling workflow that analyzes internal strain...
