Once a restricted military zone, the Akhaltsikhe-Aspindza region within the Samtskhe-Javakheti province of Georgia is now the focus of archaeological investigations. This paper brings together the main data from three years of fieldwork at the ancient site of Chobareti, situated at 1610 metres above sea level, which has so far revealed a Kura-Araxes settlement and burials, and a late Antique/Medieval stronghold.

Recent excavation at the site of Chobareti (1615 m a.s.l., South Caucasus Mountains) reveals an important Kura-Araxes settlement and eleven burials so far, for which a first multi-proxies approach was conducted to understand both exploitation of plants and human dietary practices in this mountainous area. Thanks to the excavation of several pits, in 2011, a well-reasoned sampling for archaeobotanical analysis, including phytoliths, pollen and non-pollen palynomorphs, charcoal, seeds and other plant macroremains was undertaken. In parallel, human, animal bones and wheat seeds were recovered in order to perform stable isotope analysis (d13C, d15N). Results show the strong presence of cereals (especially naked wheat, as a hexaploid form, and emmer), highlighting the role played by cereal growing in the Kura-Araxes farming activities. Plant macroremains, but also phytoliths recovered in pits, reflect processing activities on the site. While animal dung seems to have been used to enhance cereal yields, different herding practices can be suggested by d15N values. Whereas d13C values and archaeobotanical data agree for a consumption of C3 plants, with no significant input in wheat for both animals and humans, a homogeneous mixed diet, with a great contribution of animal protein source (meat, secondary products) has been observed.
Geomorphic response and 14C chronology of base level changes induced by Late Quaternary Caspian Sea mobility (middle Kura Valley, Azerbaijan). 2015

Recent geomorphological studies in Azerbaijan reveal the importance of climato-eustatic influences on landscape changes in the Caspian Sea Basin during the last 40 ka. Radiocarbon-dated fluvial landforms show that the paleohydrosystem of the middle Kura valley and tributaries responded to regressive and transgressive phases of the Caspian Sea. Chrono-sequences and landforms secured by 32 radiocarbon ages show strong correspondence between fluvial sediment accumulation and oscillations of base level in the Caspian Sea. Six phases of valley floor aggradation (e.g. 27,000–13,000; 11,000–3200; 2900–2100; 1600–1000; 400–150 cal. yr BP) and seven phases of fluvial incision (> 37,000; 37,000–27,000; 13,000–11,000; 3200–2900; 2100–1600; 1000–400; 150–0 cal. yr BP) are recorded. Morphodynamics of the fluvial landscape show a strong correspondence with fluctuation in sea levels in the Caspian Sea: the major Upper Pleistocene–Late Glacial Khvalynian (c.a. 26,000 to 12,400 cal. yr BP) and various Holocene transgressions as well as the Mangyshlak (c.a. 12,000 cal. yr BP) and Derbent (6th–12th century AD) regressions. These data contribute to refining the Caspian relative sea-level curve for the last 30 ka using the chronology of changes in the aggradation or incision in the connected fluvial system.
