“…Although, strontium data are lacking for this area, the stratigraphy is similar to that described for the Hatay Graben, indicating that the gypsums in the Nahir El-Kabi half-graben could belong to the RLG. Similar successions have been described for the Messinian evaporites in a number of sub-basins on Cyprus -the Polemi and Pissori sub-basins in the west and the Maroni sub-basin in the south (e.g., Eaton, 1987;Follows, 1992;Payne and Robertson, 1995;Robertson et al, 1995;Rouchy et al, 2001;Krijgsman et al, 2002;Manzi et al, 2015). In the western Polemi and Pissouri Basins, Tortonian marl successions reflect the progressive shallowing from ~ 500 m at Tortonian/Messinian boundary to < 100 m water depth and marine isolation leading up to the onset of evaporite deposition during the MSC (Kouwenhoven et al, 2006).…”

“…The lower unit is predominantly composed of finely-laminated gypsum with evidence for turbidity currents, slumping and debris flows, indicative of sediment reworking down a slope into deeper water. The mega-rudite breccia is formed of metre-scale blocks of fine-grained gypsum in a gypsiferous mark matrix, which Robertson et al (1995) interpret as large-scale tectonically induced slumping but Rouchy et al (2001) interpret as the result of karstic dissolution. The overlying upper unit is composed of selenitic gypsum and marl, interpreted as having formed in relatively shallow water.…”

The Hatay Graben is one of three easternmost basins in the Mediterranean that preserve sediments that span the Miocene-Pliocene boundary, including gypsums from the Messinian Salinity Crisis (MSC). Here we integrate existing data and present new sedimentological and micropalaeontological data to investigate the palaeoenvironments of late Miocene to early Pliocene deposits and place this important area into a regional stratigraphic framework. Six sections are described along a ~ W -E transect illustrating the key features of this time period. Late Miocene (Pre-MSC) sediments are characterised by open marine marls with a benthic foraminiferal fauna suggestive of water depths of 100 -200 m or less. Primary lower gypsum deposits are determined to be absent from the graben as sedimentological and strontium isotopes are characteristic of the resedimented lower gypsums. The intervening Messinian erosion surface is preserved near the basin margins as an unconformity but appears to be a correlative conformity in the basin depocentre. No Upper Gypsums or 'Lago-Mare' facies have been identified but available data do tentatively suggest a return to marine conditions in the basin prior to the Zanclean boundary. Sediments stratigraphically overlying the Messinian gypsums and marls are coarse-grained sandstones from coastal and Gilbert-type delta depositional environments. The Hatay Graben is not only strikingly similar to Messinian basins on nearby Cyprus but also to the overall model for the MSC, demonstrating the remarkable consistency of palaeoenvironments found in marginal basins across the region at this time. This research also raises questions as to the timing of the Mediterranean reflooding and the significance of the widespread mega-breccias of the resedimented gypsum deposits.

“…It provides one of the most continuous sedimentary successions related to the MSC, comprising the pre-evaporitic, evaporitic and post-evaporitic deposits which cover the period from the late Tortonian up to the early Pliocene Orszag-Sperber et al, 2009). Palaeodepth estimations in the Pissouri Section are based on foraminifera, bivalves and gastropods (Rouchy et al 2001;Krijgsman et al, 2002;. A progressive shallowing occurred from approximately 500 m in depth during the Tortonian and Early Messinian to very shallow water conditions during the late Messinian.…”

“…With the beginning of the Pliocene, deeper water conditions were re-established (Rouchy et al, 2001;Krijgsman et al, 2002). The subsequent tectonic opening of the Strait of Gibraltar in the early Pliocene (Rohling et al, 2009) and ensuing marine transgression (Rouchy et al, 2001;Soria et al, 2008) signifies the initiation of sedimentation (marine, grey clayey silts).…”

Since this episode, a general pattern of regression is documented in the sedimentary succession of Cyprus manifested in the transition from marine clayey silts through to fan delta deposits, ultimately culminating in raised beaches and alluvial fans.…”

The Bergell intrusion (European Alps) was one of the first locations where thermochronometry was used to resolve changes in erosion rate, yet, relating these changes to variations in climate or in local tectonics remains challenging. One approach that enables changes in erosion rate to be related to changes in climate or rock uplift rate is to utilize landscape evolution models, as topographic response to these forcing parameters is unique. Furthermore, low temperature thermochronometric systems have the potential to resolve topography through time and thus topographic response. We present new (U-Th)/He data for samples collected across 2 km of relief from the Bergell. The ages range from $2 to $16 Ma and define an age elevation with an apparent exhumation rate of 0.1 km/Myr. In order to infer erosion rates, we use a thermokinematic model to solve the heat equation in the crust, track material points through time and predict thermochronometric data. Paleo-topography and erosion rate are parameterized using the stream power model. We find that rock uplift rates were 0.4 km/Myr from $25 to $20 Ma and subsequently decreased to 0.05 km/Myr. This results in a gradual decrease in erosion rate from rates of 0.4 to 0.1 km/Myr. A recent increase in rock uplift rate at $4 Ma to $0.6 km/Myr is required to explain the youngest ages and high topographic relief.
