“…Another problem that is often discussed in the interpretation of FTBs with evaporites is whether the observed structures can be explained only by thrust and fold tectonics without the need for preexisting diapirs (e.g., Kamberis et al., 2022; Liesa et al., 2023; Lykakis et al., 2021). Our interpretation has demonstrated the existence of preorogenic diapirs of different shapes and orientations, conditioning the final style of the FTB.…”

The Ionian Zone (IZ) is one of the key elements of the fold and thrust belt (FTB) of the Albanian and Hellenides orogen and contains large outcrops of Triassic evaporites. The IZ consists of various thrust sheets with a general westward vergence, stacking over the Apulian and Pre‐Apulian zones, and repeating a thick carbonate sequence of Upper Triassic to Eocene age. Thrusting becomes younger toward the west with a piggyback sequence, starting during the latest Oligocene Epoch in the Internal Ionian and ending in the Pliocene in the External Ionian. We have studied the IZ in southern Albania and northwestern Greece using field observations and borehole data and by fully interpreting a recently acquired 2D seismic data set. Our objectives are to establish the geometry and nature of the contacts associated with the major Triassic outcrops, to unravel precursor salt diapirs, and to assess their role during the Alpine contraction. Salt structures include gentle salt pillows, isolated salt plugs and diapirs, thrust welds, and salt walls. Combining these observations with experimental modeling results, we show how these structures control the geometry and kinematics of the Alpine thrusts or the location and kinematics of recent strike‐slip faults. Salt minibasins have also been identified, demonstrating salt mobility conditioned Mesozoic sedimentation in the Ionian Basin. The use of salt‐tectonics principles to evaluate the structural style and evolution of the IZ FTB also opens new directions for interpreting the subsurface structure and evolution of the region.

“…Extensional tectonics controlled its geometry, the location of depocentres and internal facies distributions (Figs 1B and 2B). Cretaceous ENE-WSW striking listric normal faults system (for example, Aliaga, Remenderuelas, Camarillas, El Bat an and Jorcas faults) laterally constrained by near-vertical, reactivated NNW-SSE striking normal faults with a high dip-slip component (Miravete, Cañada Vellida, Alpeñ es and Ababuj faults) were the main structures controlling the accumulation of the Lower Cretaceous units (Soria, 1997;Liesa et al, 2000Liesa et al, , 2004Liesa et al, , 2006Liesa et al, , 2019Liesa et al, , 2023Navarrete et al, 2013a). In this sub-basin, latest Jurassic synrift sedimentation was dominated by shallow marine to coastal carbonates (Cedrillas and Aguilar del Alfambra formations; Aurell et al, 2016Aurell et al, , 2019Liesa et al, 2019), in contrast to the subsequent terrestrial and lacustrine sedimentation that occurred during the earliest Cretaceous (Galve and El Castellar formations; Soria, 1997;Mel endez et al, 2009;Aurell et al, 2016).…”

“…Outcrop successions of the Camarillas Formation are hundreds of metres thick and can be steeply dipping along exposed anticlines (Liesa et al ., 2023). Unmanned aerial vehicle (drone) imagery provides a new tool for documenting the architectural variability of facies associations (FA) within these dipping strata.…”

The Lower Cretaceous (Barremian) Camarillas Formation in the Galve Sub‐basin of eastern Spain is an exceptionally muddy, synrift, aggradational then retrogradational paralic succession. Deposition within these arid, equatorial paralic systems was strongly controlled by crustal rifting of the Iberia plate linked to the geodynamic evolution of the Atlantic Ocean, the Bay of Biscay and the Tethys Ocean. Although synsedimentary extensional tectonics controlled thickness and facies distributions, the parasequence stacking patterns point to a superimposed high‐order allogenic control on the paralic succession. Field data and drone imagery are combined to document changes in sedimentology and three‐dimensional stratigraphic architecture of these deposits to interpret changes in depositional environments as this basin filled. Three evolutionary stages are identified: (i) tide‐dominated estuary; (ii) mixed‐energy estuary, with a well‐developed wave‐dominated barrier island system; and (iii) barrier island–tidal inlet suite. An exceptional record of back‐barrier‐island depositional interactions is preserved in this high‐subsidence, extensional‐basin setting, including deposition of washover fans, flood‐tidal deltas and ebb‐tidal deltas. Drone‐derived imagery facilitates three‐dimensional architectural characterization of these complex paralic deposits, including multi‐episodic tidal inlets, and correlation of basin scale stratigraphic markers. Spatio‐temporal interactions between climate change, sea‐level variations and rift‐related subsidence generated complex estuarine and barrier island geobodies. The general transgressive trend recorded in the Camarillas Formation correlates well with global eustatic sea‐level rise during the Barremian.
