ABSTRACT. The absolute chronology of the Kura-Araxes (KA) culture in the Southern Caucasus still represents 7 a challenge due to the fragmentation and inadequacy of the radiocarbon record, as well as the inconsistencies in 8 material typologies in the region. Recent archaeological fieldwork at the site of Aradetis Orgora in the Shida Kartli 9 region of Georgia revealed four occupation levels dating to the KA II phase according to the local relative chronol-10 ogy.14 C samples were collected from reliable contexts and further selected according to reliability criteria, taking into 11 account both archaeological issues and lab procedures. FTIR was applied in order to determine the preservation of 12 charcoals and to monitor the efficiency of lab treatments on all the samples. Only accurate 14 C measurements were 13 selected for Bayesian analysis incorporating stratigraphic information. Two models were run, the second of which 14 simulated intervals corresponding to unexcavated stratigraphy or due to a lack of samples. In this article, the
