Salt tectonic processes in rift basin are mainly driven by sub- and supra-salt faulting and sedimentary loading. However, since the formation of a rift basin is often accompanied and followed by thermal subsidence, flanks of the rift basin are tilted, which induces an additional basinward directed driver for salt tectonics. We designed a new experimental analog apparatus integrating the processes of sub-salt graben extension and tilting of the flanks so that their overlapping effects on the deformation of a viscous substratum and the brittle overburden can be simulated. In total, seven experiments were performed in the analog laboratory of the Institute of Geophysics of the Czech Academy of Science (Prague, Czech Republic) and presented in the paper related to this data publication. The experimental surface was recorded by stereoscopic cameras. Images were acquired and processed by the StrainMaster© (LaVision GmbH) 3D digital image correlation (DIC; Davis 10.2) software. The data set presented here includes(1) data of the DIC:- Displacement and strain maps showing final displacement (total displacement, x-displacement, z-displacement) and strain (normal strain in x-direction) observed at the experimental surface as well as averaged values of these parameters related to experimental time(2) data related to the scaling procedure:- Data of the dimensionless Argand number and Brittle-ductile-coupling- Data of the density of natural sediments and of analog materialsDetailed descriptions of the experiments, method and results can be found in Warsitzka, et al. (2021) to which this data set is supplement. The subfolders in the data are named according to the experiments in the related paper.

A rock salt-lamprophyre dyke contact zone (sub-vertical, NE-SW strike) was investigated for its petrographic, mechanic and physical properties by means of anisotropy of magnetic susceptibility (AMS) and rock magnetic properties, coupled with quantitative microstructural analysis and thermal mathematical modelling. The quantitative microstructural analysis of halite texture and solid inclusions revealed good spatial correlation with AMS and halite fabrics. The fabrics of both lamprophyre and rock salt record the magmatic intrusion, "plastic" flow and regional deformation (characterized by a NW-SE trending steep foliation). AMS and microstructural analysis revealed two deformation fabrics in the rock salt: (1) the deformation fabrics in rock salt on the NW side of the dyke are associated with high temperature and high fluid activity attributed to the dyke emplacement; (2) On the opposite side of the dyke, the emplacement-related fabric is reworked by localized tectonic deformation. The paleomagnetic results suggest significant rotation of the whole dyke, probably during the diapir ascent and/or the regional Tertiary to Quaternary deformation.
