“…The Anti-Atlas was the location of the Eburnian, Pan-African, and Hercynian orogenies [ 34 , 35 ], which succeeded each other in time during the Paleoproterozoic, Mesoproterozoic, Neoproterozoic, and Paleozoic respectively [ 36 ]. According to the lithostratigraphic classification of Thomas et al [ 37 ], the Proterozoic basement consists of the oldest rocks of the Anti-Atlas.…”

“…The salt basin in this area was preceded by a basin of carbonate sedimentation, when numerous isolated carbonate massifs were formed, widespread throughout Central Asia [8]. Salt accumulation in the second half of the Permian period was halted by the invasion of red-colored rocks, which also occurred over a wide area [9][10][11]. In this paper, we fill this gap in the research through our analysis of the reasons for the formation of the salt basin on the territory of the Caspian depression in the Kungurian time at the end of the Early Permian epoch.…”

This article examines the geotectonic and sedimentary features of the Upper Devonian–Carboniferous–Permian deposits of the North Caspian basin, represented by deposits of marine Paleozoic-isolated carbonate platforms formed during the subsidence of the basement on the passive continental margin. The top is covered by thick salt-bearing Kungurian deposits from the end of the Early Permian epoch. The formation of carbonate platforms is associated with a major tectonic restructuring of the basin at the turn of the Caledonian and Hercynian eras, when the Paleo-Tethys Ocean was formed and isolated carbonate islands began to grow in an open marine environment. The central part of the depression experienced a long and gradual subsidence that spanned the entire Paleozoic era and the beginning of the Mesozoic era. In the south and east, from the Devonian to the Permian periods, barriers were formed in the form of island carbonate massifs that separated the North Caspian basin from the Paleo-Tethys Ocean. During the formation of the salt-bearing basin, these barriers limited water exchange and ensured a one-way influx of sea water from the open ocean. As a result, at the end of the Permian period, thicker salts accumulated; however, during the collision of the continental massifs, an invasion of many kilometers of redbeds occurred. They initially stopped salt accumulation; however, gradually, in the north of the Caspian Sea during Roadian times, the salt accumulation continued. The post-Roadian time is associated with the influx of large quantities of redbed sediments, which caused gravitational instability in the underlying salt, and salt tectonics began with the formation of domal structures.
