“…Prior to shortening, settings such as the southeast portion of the Precaspian Basin, Kazakhstan (e.g. Duffy et al., 2017; Fernandez et al., 2017; Jackson et al., 2020) and the central portion of the Sivas Basin (central domain), Turkey (Callot et al., 2014; Kergaravat et al., 2016, 2017; Legeay et al., 2019; Ribes et al., 2017; Ringenbach et al., 2013), are interpreted to have had a high salt volume (Figure 1b) with a polygonal network of salt walls surrounding isolated minibasins in map‐view. Isolated‐minibasin systems are less mechanically rigid during regional shortening than isolated‐diapir settings, given the minibasins are essentially disconnected from one another and mobile (e.g.…”

Shortening styles in salt-influenced basins can vary markedly, with the volume and distribution of salt prior to shortening being a key control. Here, we use a suite of physical models to examine styles of thin-skinned regional shortening in settings where the preshortening structure comprised minibasins surrounded by salt ('isolated- Highlights• In settings with isolated minibasins and a high salt volume, shortening induces salt flow.• The flow of salt contributes to the translation, tilt and rotation of minibasins during shortening.• A variety of factors control the amount and timing of minibasin translation, tilt and rotation during shortening.• The controls include, among others: boundary conditions, salt pressures, basesalt relief and whether primary and secondary welds have formed.• Fold-and-thrust belts in salt basins can vary in style, being strongly influenced by the volume and distribution of precursor salt.

“…The overlying Oligocene Selimiye Formation includes reddish to greenish sandstone-shale and thick massive gypsum, deposited in fluvial, playa, and lake settings (Kurtman, 1973;Poisson et al, 1996;Çiner et al, 2002;Ribes et al, 2015) (Figures 3 and 4). The Karayün Formation, assigned a Chattian age according to assemblages of benthic and planktonic foraminifera, was deposited in fluvial, lacustrine, playa, and lake environments indicating an inception of salt tectonism, which gave rise to the formation of at least 20 minibasins such as Eğribucak, Emirhan, Bingöl, and Eskiboğazkesen (Ringenbach et al, 2013;Callot et al, 2014;Ribes et al, 2015;Kangal et al, 2016;Kergaravat et al, 2016;Pichat et al, 2016).

Introduction The Miocene is an epoch in earth history before the development of the Northern Hemisphere ice sheet. It was characterised by transgression-regression events leading to the opening and closing of seawater in Europe (Rögl, 1998; Zachos et al., 2001; Meulenkamp and Sissingh, 2003). The early Miocene, which is the main subject of this study, is a critical period between Oligocene mainly "icehouse" climates and the middle Miocene climatic optimum (MMCO) (Flower and Kennet, 1994). Some authors indicated that relatively warm and ice-free conditions persisted during the early Miocene (Zachos et al., 1997; Mosbrugger et al., 2005). Conversely, other authors claimed that this warm period was stopped by several cooling and glaciation events, especially for the high latitudes (

“…Its marine evaporites, which precipitated during the Bartonian -Priabonian (Pichat et al, 2018), have only been described locally as the Tuzhisar Formation in the westernmost part of the basin, where gypsiferous accumulations are less than 100 m-thick (Gündogan et al, 2005). In the central part of the basin, the original thickness of the evaporitic succession remains unknown, but must have been quite thick enough to allowed the development of at least two generations of salt-withdrawal mini-basins (up to kilometer-thick) during the Oligo-Miocene (Ringenbach et al, 2013;Callot et al, 2014;Ribes et al, 2015Ribes et al, , 2016Ribes et al, , 2016Kergaravat et al, 2016Kergaravat et al, , 2017Kergaravat et al, , 2017Legeay et al, 2020;Pichat et al, 2019).…”

Sivas foreland basin in Turkey recorded a salinity crisis during the Late Eocene resulting in evaporite accumulations thick enough to trigger intense halokinesis during the Oligo-Miocene. The salinity crisis is studied thanks to three sedimentological sections crossing the transition from the last marine deposits (Bözbel Formation) to the overlying evaporitic facies (Tuzhisar Formation) preserved from halokinetic deformations. The top of the Bözbel Formation presents flood-generated hyperpycnites developed in pro-delta to delta front settings. In the central part of the basin, such facies become increasingly sediment-starved with azoic calcareous facies interlayered with organic-rich shales. Such facies are ultimately capped by thick accumulations of gypsiferous turbiditic lobe deposits. Southward, the foredeep was partly isolated from the central domain due to the propagation of an anticline. There, the basal siliciclastic turbidites become increasingly gypsum-rich and are capped by a 45 m-thick mass-transport deposit enclosing olistoliths of gypsum and of ophiolitic rocks. Such gravity collapse deposits evolve upward to the same gypsiferous turbiditic lobes observed northward. Both transitional facies record the progressive confinement of the basin from the sea, likely due to the northward propagation of the fold-and-thrust belt located farther south. The evaporites started to precipitate in piggy-back evaporitic basins, along the highs of the fold-and-thrust belt, before being reworked gravitationally in the foredeep to the north, producing the high to low density gypsum turbidites. Finally, from north to south, the reworked evaporites are extensively covered by a >100 m thick, chaotic, prismatic gypsum mass likely resulting from the hydration of anhydrite grains left as a residual phase after the leaching of a significant amount of halite. The latter formed in a hypersaline marine-fed basin and have lately allowed mini-basin salt tectonics during Oligo-Miocene times.
