The analysis of the reliability of different scenarios for the formation of the vertical structure of the waters of the Caspian Sea, obtained from the distribution of transient tracers (CFC-11, CFC-12, 3H and 3He) at the deep-water stations of the Middle and Southern Caspian within the framework of international integrated isotope-geochemical studies during the maximum sea level rise in 1995–1996. Taking into account the available hydrometeorological data and the characteristics of water dating using transient tracers, it was concluded that after large-scale gravitational convection in the Middle Caspian caused by anomalous cooling of surface waters in the Northern Caspian at the end of the winter of 1976, a structure of water masses was formed that excluded deep water ventilation in the Middle and South Caspian Sea until the mid-90s.

Until about two decades ago, the Neolithic of north-east Iran was known only from a few brief excavation reports: the sites of Yarim Tappeh (Stronach 1972) and Turang Tappeh (Deshayes 1967) on the Gorgan Plain, and preliminary reports of large-scale excavations at the twin mound of Sang-e Chakhmaq in the southern foothills of the eastern Alborz Mountains (e.g. Masuda 1984). In the absence of absolute chronologies, these sites were dated by ceramic assemblages to the sixth millennium BC, and were considered to relate to the so-called ‘Jeitun Culture’ of southern Turkmenistan (Figure 1; Roustaei 2016a).
