“…A further option to add 3D complexity is the inclusion of different along-strike geometries of base plates, such as oblique VD's (Panien et al 2005;Ustaszewski et al 2005;Munteanu et al 2014;Jara et al 2015Jara et al , 2018Granado et al 2017, Wang et al 2017Deng et al 2019), transfer fault structures (Konstantinovskaya et al 2007, Likerman et al 2013) and pull-apart 380 systems (Wang et al 2017, Fig. 6g-i).…”

“…4c, d). Patches of viscous materials are used as a handy method to distribute crustal deformation above an otherwise (too) strongly localizing VD in crustal-scale base plate models (Brun & Nalpas 1996;Del Ventisette 2005, 2006Sani et al 2007;Pinto et al 2010;Likerman et al 2013;Jara et al 2015Jara et al , 2018, even though deformation may also be focussed along the edges of these patches. Other researchers have applied a viscous layer throughout the model to simulate a ductile lower 395 crustal layer underlying the brittle upper crust (Konstantinovskaya et al 2007;Mattioni et al 2007;Bonini et al 2012;Munteanu et al 2013).…”

“…14j-k). Other variations are likely due to different degrees of extension and compression, as well as the symmetry or asymmetry of compression (Likerman et al 2013;Munteanu et al 2014;Jara et al 2015Jara et al , 2018, see section 4.5.2). Vially et al (1994) and Letouzey et al (1995) have explored another setup, involving a rigid footwall block next to a pre-915 made basin containing a brittle infill on top of a viscous layer (Fig.…”

Abstract. Basin inversion involves the reversal of subsidence in a basin due to compressional tectonic forces, leading to uplift of the basin’s sedimentary infill. A thorough understanding of basin inversion is of great importance for scientific, societal and economic reasons. Analogue tectonic modelling forms a key part our efforts to improve our understanding of basin inversion processes, and researchers have conducted numerous studies on this topic. In this review paper we recap the advances in knowledge of basin inversion tectonics acquired through analogue modelling studies, providing an up-to-date summary of the state of analogue modelling of basin inversion. We describe the different definitions of basin inversion that are being applied by researchers, why basin inversion has been historically an important research topic, and what the general mechanics involved in basin inversion are. We subsequently treat the wide range of different experimental approaches used for basin inversion modelling, with attention to the various materials, set-ups and techniques used for monitoring and analysing the model results. Our new systematic overviews of generalized results reveal the diversity of model results, depending greatly on the chosen set-up, model layering and (oblique) kinematics of inversion, as well as 3D along-strike structural and kinematic variations in the system. We show how analogue modelling results are in good agreement with numerical models, and how these results help to better understand natural examples of basin inversion. In addition to reviewing the past efforts in the field of analogue modelling, we also shed light on future modelling challenges and identify a number of opportunities for follow-up research. These include the testing of force-boundary conditions, adding geological processes such as sedimentation, transport and erosion, applying state-of-the-art modelling and quantification techniques, and establishing best modelling practices. We also suggest expanding the scope of basin inversion modelling beyond the traditional upper crustal "North Sea style" of inversion, which may contribute to the on-going search for clean energy resources. It follows that basin inversion modelling can bring valuable new insights, providing a great incentive to continue our efforts in this field. We therefore hope that this review paper will form an inspiration for future analogue modelling studies of basin inversion.

Lithological heterogeneities in a rock series deformed by the development of a fold-and-thrust belt (FTB) affects the pattern of the resulting structures. We present a series of analogue experiments to determine the effect caused on the deformation pattern of a FTB by the presence of cohesive bodies, like plutons or basement blocks that oppose greater resistance than the host rocks to contractional deformation. The influence of these bodies on the deformation pattern of the FTB was studied by incorporating discordant bodies with different cohesions within a stratified granular sequence with negligible cohesion. We describe two sets of experiments in which the inserted body presents low (Co1) and high (Co2) cohesion respectively. The experiments show a tendency of the structural pattern to curve around the inserted body and to migrate towards the deformation front or the foreland, even when the cohesive body is not exposed. In the first case (Co1) the thrusts cut across the cohesive body, while in the second one (Co2) the cohesive body is not faulted, but transferred towards the deformation front along a basal detachment. Comparison of these results with natural examples at different scales shows a high degree of coincidence in the structural patterns recognized in both cases. Two of the main characteristics of these patterns are the tendency of the thrust faults traces to avoid the cohesive body and adopt the geometry of its distal edge. In order to explain curvatures in natural structural patterns in fold-and-thrust belts, we suggest consider the presence of unexposed bodies with higher strength than their environment.
