“…9c). The formation of such a popup structure is also observed in the models by Lebinson et al (2020) with a similar basement block geometry, but which did not involve an initial extensional phase. Buchanan and McClay (1991) also show how, in the presence of a thick post-rift/syn-inversion sequence, the major fault along the basement block can change to a shallower angle when propagating into these shallower sequences (footwall cut-off).…”

“…Some researchers simplify the modelling procedure by establishing the basin or normal fault(s) already during model preparation (Fig. 5j), obtaining inversion by subsequently moving a backstop into the model (Sassi et al, 1993;McClay et al, 2000;Panien et al, 2006a;Marques and Nogueira, 2008;Di Domenica et al, 2014;Martínez et al, 2016Martínez et al, , 2018Martínez and Cristallini, 2017;Lebinson et al, 2020). Such backstop models can be combined with fixed basement blocks that represent the footwall block of a rift boundary fault or half-graben structure (Vially et al, 1994;Letouzey et al, 1995;Philippe, 1995;Lebinson et al, 2020, Fig.…”

“…Various authors have used pre-built basins or faults that were subsequently compressed by moving a backstop into the model for the simulation of basin inversion (Sassi et al, 1993;Panien et al, 2006a;Marques and Nogueira, 2008;Di Domenica et al, 2014;Martínez and Cristallini, 2017;Lebinson et al, 2020). McClay et al (2000) instead used a first phase of differential sedimentary loading to create rift basins to be inverted by a moving backstop.…”

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. Detailed knowledge of basin inversion is of great importance for scientific, societal, and economic reasons, spurring continued research efforts to better understand the processes involved. Analogue tectonic modelling forms a key part of these efforts, and analogue modellers have conducted numerous studies of basin inversion. In this review paper we recap the advances in our knowledge of basin inversion processes 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 model monitoring and analysing the model results. Our new systematic overviews of generalized model results reveal the diversity of these results, which depend greatly on the chosen set-up, model layering and (oblique) kinematics of inversion, and 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 researchers 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 ongoing 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.

“…Physical simulation experiments have long served as an important approach for hydrocarbon exploration. Particularly, physical simulation experiments on structural deformation have been extensively applied to examine the deformation mechanism of thrust belts (Cruz et al, 2010; Deng et al, 2021; Koyi et al, 2016; Lebinson et al, 2020; Luth et al, 2013; Yin et al, 2011). Meanwhile, numerous studies based on the physical simulation of hydrocarbon accumulation have been conducted to reveal the process and mechanism of hydrocarbon accumulation (H. Y.

The piggyback thrust wedge is a common structural style in thrust belts, which controls the lateral arrangement of hydrocarbon distribution. This study conducted physical simulation experiments of structural deformation and hydrocarbon accumulation by using the piggyback thrust wedge as the geological model. According to the experimental results, hydrocarbon accumulation patterns were obtained by investigating the evolutionary history of the fault‐sealing performance while inverting the coupling relationship between the fault evolution and hydrocarbon accumulation. The structural deformation experiment showed that the evolution of the fault displacement and dip angle was characterized by gradual and staged progress. The kaolin smear continuity deteriorated with fault evolution. The soybean oil accumulation experiment demonstrated that the fault‐sealing performance in the rear of the thrust wedge was inferior to that in the front. Hydrocarbon migration was mostly lateral in the front of the thrust wedge and mainly vertical in the rear. Quantitative analysis showed that the fault‐sealing performance had three closed, partially closed, and open stages, which gradually deteriorated with the structural evolution. Three hydrocarbon accumulation patterns were identified in the piggyback thrust wedge: synchronized, adjustment, and non‐adjustment patterns. The evolution of the structural deformation and faults‐sealing performance resulted in spatio‐temporal differences in hydrocarbon accumulation in the thrust belts of central‐western China. The front of the thrust wedge had a higher exploration potential than the rear.
