Short summary
Short summary
This work focuses on the control of accommodation zones on extensional and subsequent inversion in salt-detached domains using sandbox analogue models. During extension, the transfer zone acts as a pathway for the movement of salt, changing the expected geometries. When inverted, the salt layer and syn-inversion sedimentation control the deformation style in the salt-detached cover system. Three natural cases are compared to the model results and show similar inversion geometries.

Short summary
Although significant progress in Early Jurassic cyclostratigraphy has been made in the last few decades, fewer studies have focused on the climatic and environmental impact of orbital cycles on the sedimentary record. This study presents an original orbitally modulated depositional model, which provides new insight into the formation of orbitally modulated organic-rich calcareous hemipelagic rhythmites accumulated in early Pliensbachian times in the northern Iberian palaeomargin.

Short summary
Short summary
Using the Asturian–Basque–Cantabrian system and analogue (sandbox) models, this work focuses on the linkage between basement-controlled and salt-decoupled domains and how deformation is accommodated between the two during extension and subsequent inversion. Analogue models show significant structural variability in the transitional domain, with oblique structures that can be strongly modified by syn-contractional sedimentation. Experimental results are consistent with the case study.

Short summary
Among sedimentary rocks, evaporites (as salt) have a particular behavior when deformed under geological forces: they flow while the others break. Such behavior controls the evolution of mountain building events. By mapping the distribution of rocks and interpreting the subsurface architecture of geological structures we were able to reconstruct the mountain building processes of an area in the Southern Pyrenees and how those evaporites flowed and accumulated.
