Radiocarbon dating, also referred to as carbon-14 dating (14C), is a method widely used in archaeology to provide the ‘absolute dating’ of organic materials (seeds, wood, bones, and so on) intended as an approximate age within a range of years. This method allows to give a more precise framework of the events at first ordered according to the stratigraply and artefacts typology (relative dating).  The amount of the unstable radioisotope carbon-14 on our planet has a relatively short half-life of 5,730 years; this means that the fraction of carbon-14 in a sample is halved over the course of 5,730 years due to radioactive decay to nitrogen-14. The process begins when an organism is no longer able to exchange carbon with its environment; therefore, by measuring the radioisotope carbon-14 we can able to approximate the date at which the organism livedA preliminary collection of seven organic samples from Tepe Qaleh Naneh, a significant prehistoric site located in the Zaribar Lake basin of Western Kurdistan, was chosen to enhance our understanding of local cultural sequences. This selection also aims to elucidate the connections between the northern central Zagros region and its neighboring areas. The limited radiocarbon dating available from Western Iran currently hinders the synchronization of fieldwork findings in this area with the cultural sequences of Mesopotamia and other regions of Iran. The Chalcolithic, especially the Late Chalcolithic-Uruk phase, is the longest and most important occupation period on the site.  The material culture found at Qaleh Naneh reflects a progressive social stratification during the Late Chalcolithic period. This evolution in social structure is probably attributed to cultural and trade exchanges with adjacent areas
