“…Physical analogue modelling techniques have been proven to provide robust simulations of a wide variety of tectonic and geological features and processes from global-or regionalscale crustal studies to outcrop and sub-metrescale processes (e.g. Cadell 1888; Hubbert 1937, Ramberg 1963Mulugeta 1988;Koyi 1997;Rahe et al 1998;Wyrick et al 2011;Byrne et al 2013;Sims et al 2013). Among the most important strengths of physical analogue modelling are: (1) the capability to model complex three-dimensional configurations; (2) the capacity to simulate discontinuous processes such as fracturing and faulting; and (3) the ability to document evolving deformation over time.…”

“…Faults produced in these analogue materials are geometrically and kinematically similar to those observed in terrestrial fault systems (Rahe et al 1998;Wyrick et al 2011;Sims et al 2013). Although the absolute values of the principal stresses are not measurable, the experiments were set up so that the maximum principal compressive stress s 1 was vertical and the relative magnitudes of the initial minimum principal stress s 3 were controlled by varying boundary constraints.…”

The Tharsis region of Mars is characterized by large volcanic and tectonic centres that have been active throughout Martian geological history, including distinct sets of graben that extend radially for distances of hundreds to thousands of kilometres. Formation of these graben has been attributed to crustal extension and/or dyke propagation. Physical analogue models using layered sand and liquid paraffin wax were constructed to test the magnitude and style of deformation in the host rock associated with dyke injection. A variety of igneous morphologies was produced, including dykes and plugs. Results suggest that, in the absence of pre-existing faults, vertical dykes do not produce significant deformation in the surrounding rock. Deformation associated with other magmatic intrusions produced primarily contractional features rather than extensional features, similar to previous numerical studies and terrestrial field investigations.Gold Open Access: This article is published under the terms of the CC-BY 3.0 license.

“…However, the mechanical modeling of pull-apart basins is complicated because of their 3-D nature. This is why analog modeling is most popular (Richard et al, 1995;McClay and Dooley, 1995;Rahe et al, 1998;McClay and Bonora, 2001;Calvez and Vendeville, 2002;Atmaoui et al, 2006). Such modeling focuses mostly on simulating pull-apart structure initiation in certain geotectonic settings (e.g., Smit, 2005;Atmaoui et al, 2006) and understanding the nature of near-surface strain distribution during basin evolution.…”

“…Welding and extrusion of the salt sequence towards the southeastern side of the basin resulted in the asymmetrical structure of the basin in cross-sections. Somewhat similar asymmetric pull-apart basins related to differing slip rates on basin margins were modelled by Rahe et al (1998).…”

Several main tectonic lineaments originating in the Alps and Dinarides merge in Central Hungary to form the Mid-Hungarian Shear Zone. As these structures are hidden beneath sub-basins of the Neogene Pannonian Basin, it has long been debated whether the tectonic style of the shear zone is mainly contractional or strike-slip. New 3D seismic data allowed a detailed analysis of one of these sub-basins, the Adony Basin, located south of Budapest. Its evolution is linked to the tectonics between the southern Tisza unit of European passive margin affinity, the northern ALCAPA block with Alpine affinity, and sheared remnants of Dinaric units in between. During the Oligocene and Early to Middle Miocene, a flexural basin related to the convergent thrusting of Dinaric-and ALCAPA-derived units was developed. On the southern side, N-NW verging thrust sheets were observed. On the opposite front, Triassic carbonates of ALCAPA were thrust several kilometres above Palaeogene formations to the SW. Dextral transpression is assumed for the Middle Miocene. Local deposition of Middle Miocene salt in the basin formed a detachment surface. Late Miocene sinistral strike-slip faulting resulted in a pull-apart basin above that part of the earlier flexural basin that has not been overthrust. The margins of the basin coincided with the fronts of earlier thrusts. Faults on the basin margins partly detached on the salt, decoupling the supra-salt basin fill from the underlying formations. Within the pull-apart basin, gravity sliding on the steep margins resulted in salt welds, detachment and roll-over folds.
